Karnak

The Karnak Temple Complex is located near Luxor, some 500 km south of Cairo, in Egypt which is mainly made of temples, chapels, pylons, and other buildings. Karnak was the ancient Egyptian Ipet-isut. This can be seen as the world’s largest ancient religious site. It consists of four main parts as Precinct of Amun-Re, Precinct of Mut, the Precinct of Montu, and the dismantled Temple of Amenhotep IV. There also are a few smaller temples and sanctuaries located outside the enclosing walls of the four main parts, as well as several avenues of goddess and ram-headed sphinxes connecting the Precinct of Mut, the Precinct of Amun-Re, and the Luxor Temple.

Lake Baikal

With an average depth of 744.4 m, Lake Baikal nicknamed as Old Sister of Sister Lakes, is the world’s oldest and deepest of lakes found in Siberia containing around 20% of the world's unfrozen surface fresh water. With a surface area of 31,722 km2, Lake Baikal is crescent in shape and provides living space o more than 1700 species of plants and animals and most of which are only found within the lake. On the eastern side of the lake reside the Buryat tribes who rear goats, camels, cattle and sheep. The first ever Russian to reach Lake Baikal was Kurbat Ivanovin.

Wulingyuan Scenic Area

When you drive away about 20km from Changsha you will find this beautiful Wulingyuan area with Zhangjiajie, Tianzi Mountain, Shuoxiyu and Yangjia Boundary. This place is unique and famous for its natural landscape which comprises of sandstones, dense forests, deep ravines and its specialty is completed with peaks, deep canyons, flowing waters, thickest forests and mysterious caves. There are around 3000 peaks of quartz sandstones with variable heights and shapes. Among them, most significant are the Camel Peak, the Drunk Stone Peak, and the Five Finger Peak. There are 32 canyons of more than 2000 meters long each and the famous ones are Jinxi Canyon, the Shentang Canyon and the Gallery Canyon. There are around 800 waterscapes in the area too. Yellow Dragon Cave is the most famous among caves and there are beautiful stalactites in these caves. 

Louvre Museum

Located on the right bank of the Seine, Louvre Museum is one of the world’s largest museums with nearly 35, 000 objects in display over 60,600 square metres. Museum is located at the Louvre Palace built in the late 12th century under Philip II. It was officially opened on 10 August 1793 with an exhibition of 537 paintings. But it was closed again in 1796 because of structural problems but was opened again in 1801. The museum’s artifacts are divided into eight curatorial departments as Egyptian Antiquities; Near Eastern Antiquities; Greek, Etruscan, and Roman Antiquities; Islamic Art; Sculpture; Decorative Arts; Paintings; Prints and Drawings.

Plitvice Lakes National Park

Founded in the Southeast Europe, Croatia, Plitvice Lakes National Park is the largest in the country extending over 296.85 square kilometers. It was founded in 1949 in the mountainous karst area at the border to Bosnia Herzegovina. The name Plitvice was designated due to the natural occurrence of lakes. Currently there are 16 lakes which are grouped into the 12 Upper Lakes and the four Lower Lakes. There have been shallow basins which were eventually filled with water constantly changing the limestone and landscape of the area. The travertine barriers decelerated and retained the flowing water. 

Alhambra

Lying on the top of the hill of the Assabica on the southeastern border of the city of Granada, Andalusia in Spain is the Alhambra; a palace complex built around mid 14th century. Alhambra reflects Moorish culture and architecture to a great extent and Alhambra reflects the colour of the red clay of the surroundings but originally it was white washed. Also evidence from Arab texts also indicates that the fortress that is seen today was built during the Nasrid Dynasty. 

Uluru

Some may be familiar with Uluru as the Ayers Rock, which is a large sandstone rock formation found in central Australia. It is about 348m high with a circumference of 9.4km. Uluru is regarded as a sacred place for the Aboriginal people. William Gosse in 19 July 1873, named this as Ayers Rock in honour of Sir Henry Ayers who was the chief secretary of South Australia then. The significance of Uluru is the ability to change colour at different times of the day and year. Another in this territory is the Kata Tjuta which is also known as Mount Olga 25km west of Uluru. 

Angel Falls

Found in Venezuela, Angel Falls is known as the world’s highest water fall. Starting from the Auyantepui Mountain in the Canaima National Park, the falls droops down to a depth of 979m from the top into the Kerep River aka Río Gauya. Due to the vast amount of height, the water usually turns into mist before catching the bottom. First ever person to fly over the falls is the US aviator Jimmie Angel. The falls was named after him. Sir Walter Raleigh is regarded as the first European to view the Falls but some say it was Fernando de Berrio; a Spanish explorer. The first westerner to reach the river that nourishes the falls is Aleksandrs Laime, also known as Alejandro Laime to the native Pemon tribe from Latvia. His climb was in 1955. He gave this river feeding the falls the name Gauja after a river in Latvia, but the Pemon-given name of the river, Kerep, is still widely used.

Stromboli

Stromboli is one of the eight Aeolian Islands found in the Tyrrhenian Sea, off the north coast of Sicily. The specialty of this specific island is that it is home to one of the three active volcanoes of Italy. It is also known as the “Lighthouse of the Mediterranean” visibly in height of 926m above sea level with three active craters at the top. Geologically this volcano is special because of its horseshoe shaped depression generated within the last 13,000 years which is known as the Sciara del Fuoco. There is a volcanic plug of basalt found at the Northeast part of the island which is believed that once had been an active volcano before Stromboli reached sea level around 200,000 BC. 

Komodo Island

Komodo is one of the islands of Indonesia that lies between the neighboring islands, Sumbawa to the west and Flores to the east with an area of 390  km². Island is home for descendants of former convicts who were exiled to the island. Given the name Komodo to this island, it is world famous because of the world's largest lizard Komodo dragon is found roaming here and other small neighboring islands. Apart from this beast, Komodo Island also has a pink beach which is supposed to be one of the seven pink beaches of the world. The beauty of the Komodo Island is not the only fact that attracts tourists but it is a polular diving station. Also Komodo Island was considered in the new seven wonders of the world since 11th Nov. 2011.

Jiuzhaigou Valley

Jiuzhaigou Valley means the valley of nine villages. It is actually a nature reserve found in the Aba Tibetan Qiang Autonomous Prefecture of Sichuan Province of Southwestern China. This valley covers an area of about 72 000 hectares and is a part of the Min Shan mountain range on the edge of the Tibetan Himalayan Plateau. The specialty we find in Jiuzhaigou valley is the colourful lakes with varying heights of water curtains. Although there are originally nine villages found here, only seven of them are still populated up to date. Anyhow their main livelihood is tourism as agriculture is not permitted within the reserve. 

Ganges at Varanasi

Ganges is the India’s most worshipped river with many religious aspects and Varanasi is well famous for Ganges and its activities and is one of the holiest cities in India. Earlier known as Banaras, Varanasi is found within Uttar Pradesh and it is truly a feast for visitors with warm welcoming citizens and heartfelt ceremonies and rich cultures woven around Ganges. 

Wat Phra Kaeo

Located in the city of Bankok, is the heart of all Buddhists in Thailand; Wat Phra Kaeo. There lies the Emerald Lord Buddha in central ubosoth and this statue is in standing form with a height of 66cm carved from a single jade stone. Only the king is allowed to touch the statue in order to change the cloak three times a year in the hope of good fortune to the country.  The roots of the statue is from India, according to legends, however its records states that it was found in Cambodia in 15th century and was moved to Laos and Vientiane and it was kept there for 215 years and at last, it was brought to Thailand in 18th century. 

Mont Saint-Michel

Found in France, one kilometer off the north-western coast near the mouth of the Couesnon River at Avranches, Mont Saint- Michel, earlier known as Monte Tombe”, can be described as a vital point of fortifications since 8th century AD. In earlier times, the bay was a land which was shaped into today’s landscape and several blocks of granite, granulite rose up which later became Lillemer, the Mont-Dol, Tombelaine and Mont Tombe, later called Mont-Saint-Michel. 

The Monasteries of Meteora

 Situated at the northwestern edge of the Plain of Thessaly, are these beautiful monasteries of Meteora extending up to a height of 313m. Meteora gives the meaning, suspended rocks or heaven above and it is supposed to be one of the most important complexes of Eastern Orthodox monasteries in Greece, second only to Mount Athos. Evidences suggest that these pinnacles were formed at least 60 million years ago. A special geographic feature seen here is that the sandstone rocks rise above from the ground. Composition of the rocks is of sandstone and conglomerate. With the time and certain factors like the withering of the rocks, they were shaped into stone pillars seen today. There is also a cave found near the foot of the cliffs. 

Hassan II Mosque

The Hassan II Mosque can be taken as the largest mosque in the country, Casablanca, Morocco and the 7th largest mosque in the world. Its minaret is however the world's tallest at 210 m. This Mosque, which is a religious building is a design the French architect Michel Pinseau and a creation by Bouygues. The Mosque stands in a way like looking out to the Atlantic. The Mosque is so huge so that it can accommodate almost 105,000 worshippers for prayers and around 25,000 inside the mosque and another 80,000 on the mosque's ground outside.

Acropolis of Athens

Also Known as the Citadel of Athens, this is so far world’s best acropolis and it is significant because it is an acropolis without a qualification. The Acropolis rises 150 m above sea level in the city of Athens as a flat-topped rock with a surface area of about 3 hectares. It was also known as Cecropia, after the legendary serpent man Cecrops, the first Athenian king. The Propylaea is known as the entrance to the Acropolis and to the south of the entrance is the tiny Temple of Athena Nike. A bronze statue of Athena, sculpted by Phidias, originally stood at its centre. At the centre of the Acropolis is the Parthenon or Temple of Athena Parthenos. East of the entrance and north of the Parthenon is the temple known as the Erechtheum. South of the platform that forms the top of the Acropolis there are also the remains of an outdoor theatre called Theatre of Dionysus. A few hundred metres away, there is the now partially reconstructed Theatre of Herodes Atticus.

Palace of Versailles

20km southwest of Paris is the beautiful country side of France;Versailles which is enchantingly famous for the castle of King Louis XIV known as Palace of Versailles. The first ever seigneur of Versailles mentioned was Hugues de Versailles and then in 1575, Albert de Gondi bought the Versailles. Gondi had invited King Louis XIII for hunting trips near Versailles during early 17th century which resulted in construction of a hunting lodge in 1624 as the king was pleased. After few years later King Louis XII gained the ownership of Versailles his son, Louis XIV became familiar with the place since he was a boy.  When Louis XIV became king, he renovated the château in Versailles which was the hunting lodge earlier into one of the biggest castles in the world. Its constructions and renovations began in 1661 using the master minds of architect Louis Le Vau, landscape architect André Le Nôtre, and painter-decorator Charles Le Brun. King Louis XIV moved the capital of France to this castle at Versailles from Paris and officially settled down there on 6 May, 1682.

BIG BEN

One of the few amazing things you can see in England is the Big Ben clock. Although we call it Big Ben, this name is actually belongs to clock’s main bell. Its official name is the Great Bell of Westminster. This is a tower found in Houses of Parliament building at the north- eastern end in London. On October 16, 1834, the old palace of Westminster was burnt in fire and as a result of the new plan of the building suggested, Big Ben was constructed. Tower is 96.3m high which is made of part brickwork with stone cladding and part cast iron. It stands on a 15m x 15m raft, made of 3m thick concrete, at a depth of 7m below ground level.  The over all tower weighs about 8,667 tonnes. And tower leans slightly to the north-west due to ground structure.

It was first placed in New Palace Yard which cracked due to striking hammer while construction in 1856. Then it was recast at White Chapel Bell Foundry. Installed into the clock tower in 1908, another crack formed. To prevent further damage to the bell it was rotated and the main hammer was reduced in weight. There are other four quarter bells which play the Westminster Quarters on the quarter hours. The four quarter bells are G sharp, F sharp, E, and B. They play a 20 chime sequence, 1-4 at quarter past, 5-12 at half past, 13-20, 1-4 at quarter to, and 5-20 on the hour. Their faces are 55m above the ground and even though it is not anymore, it still holds the title, “World’s largest four faced chiming clock”. The dials were designed by Augustus Pugin and the minute hand is 14’ long while the hour hand is 9’ long. There is a Latin inscription at the base saying 'DOMINE SALVAM FAC REGINAM NOSTRAM VICTORIAM PRIMAM'. It means 'Lord save our Queen Victoria I'. The clock sprang into life for public on September 7th, 1859.

Registan


Registan meaning “Sandy place” in Persian, was the heart of ancient city Samarkand, now in Uzbekistan. Registan can be taken as a public place of importance given for executions, gathering place for royal proclamations heralded by blasts on enormous copper pipes called dzharchis. The three madrasahs which means school, of the Registan are: the Ulugh Beg Madrasah (1417–1420), the Tilya-Kori Madrasah (1646–1660) and the Sher-Dor Madrasah (1619–1636). 
The first one, Ulugh Beg Madrasah has its imposing portal with lancet arch facing the square where are flanked by the high well-proportioned minarets. The mosaic panel over the entrance arch is decorated by geometrical stylized ornaments. The square-shaped courtyard includes a mosque and lecture rooms and is fringed by the dormitory cells in which students lived. There are deep galleries along the axes. Originally this was a two-storied building with four domed lecture rooms at the corners. The madrasah was one of the best clergy universities of the whole Muslim Orient of the 15th Century CE. Abdurakhman Djami, a prominent poet, scientist and philosopher studied there. Ulugh Beg himself gave lectures there. During Ulugh Beg's government the madrasah was a centre of secular science.

Sistine Chapel

   Found in Apostolic Palace, Sistine Chapel is the official residence of the Pope in Vatican City. Veteran artists like Michelangelo, Sandro Botticelli, Pietro Perugino, Pinturicchio have drawn frescoes in this chapel where it is well known for architecture and decorations. Under the patronage of Pope Julius II, Michelangelo painted 1,100 m2 (12,000 sq ft) of the chapel ceiling between 1508 and 1512. The painting drawn in the ceiling; The Last Judgment (1535-1541) is supposed to be Michelangelo’s crowning achievement in painting. The chapel’s name is from Pope Sixtus IV who restored the old Capella Magna in 1477-1480. The paintings were completed in 1482, and on the 15 August 1483, Sixtus IV celebrated the first mass in the Sistine Chapel for the Feast of the Assumption, at which ceremony the chapel was consecrated and dedicated to the Virgin Mary.
The main function of the chapel could be denoted as the venue for the election of each successive pope in a conclave of the College of Cardinals. On the occasion of a conclave, a chimney is installed in the roof of the chapel, from which smoke arises as a signal. If white smoke appears, created by burning the ballots of the election, a new Pope has been elected. If a candidate receives less than a two-thirds majority, the cardinals send up black smoke which means that no successful election has yet occurred. The conclave also provided for the cardinals a space in which they can hear mass, and in which they can eat, sleep, and pass time abetted by servants. Canopies for each cardinal-elector were once used during conclaves as a sign of equal dignity. When a new pope is being elected, he gives his new name and at this, the other Cardinals would tug on a rope attached to their seats to lower their canopies.

Rocky Mountains


   Spread over western North America, the Rocky Mountains stretch more than 4,830 km from the northernmost part of British Columbia, in western Canada, to New Mexico, in the southwestern United States. This mountain range must have been formed from 80 million to 55 million years ago by the Laramide orogeny. Since then, erosion by water and glaciers has sculpted the mountain range into dramatic valleys and peaks. At the end of the last ice age, humans started to inhabit the mountain range. Today much of the mountain range is protected but still it is a popular tourist destination mainly for hiking, camping, mountaineering, fishing, and hunting, skiing, and snowboarding.
Before the mountains were raised by tectonic forces, the rocks in the Rocky Mountains were formed. The oldest rock is Precambrian metamorphic rock that forms the core of the North American continent. There is also Precambrian sedimentary argillite, dating back to 1.7 billion years ago. In the southern Rocky Mountains, near present-day Colorado, these ancestral rocks were disturbed by mountain building approximately 300Ma, during the Pennsylvanian. This mountain building produced the Ancestral Rocky Mountains. They consisted largely of Precambrian metamorphic rock forced upward through layers of the limestone laid down in the shallow sea. The mountains eroded throughout the late Paleozoic and early Mesozoic, leaving extensive deposits of sedimentary rock.

English Channel


Separating the Northern France and Southern England lies the English Channel also joining the North Sea to the Atlantic. It is about 560 km long and varies in width from 240 km at its widest, to only 34 km in the Strait of Dover. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some 75,000 km2. It is believed that the name “English Channel” was from the designation "Engelse Kanaal" in Dutch sea maps from the 16th century onwards. It was also known as the British Sea, and it was called the "Oceanus Britannicus" by the 2nd century geographer Ptolemy. The channel has been a huge advantage for British specially acting as a natural defense blocking many invasions and as a link between cultures of neighbouring countries.
Around 10,000 years ago, before the end of the Devensian glaciations, the British Isles were part of continental Europe. During this period the North Sea and almost all of the British Isles were covered with ice. The sea level was about 120 m lower than it is today, and the channel was an expanse of low-lying tundra, through which passed a river which drained the Rhine and Thames towards the Atlantic to the west. As the ice sheet melted, a large freshwater lake formed in the southern part of what is now the North Sea. As the melt water could still not escape to the north the outflow channel from the lake entered the Atlantic Ocean in the region of Dover and Calais.

Andes


   Spreading across countries Argentina, Bolivia, Chile, Colombia, Ecuador, Peru and Venezuela, Andes is the world's longest continental mountain range. In length wise, the Andes is split into several ranges, which are separated by intermediate depressions. It is a continual range of highlands along the western coast of South America. This range is about 7,000 km long, about 200 km to 700 km wide and of an average height of about 4,000 m. Its highest peak, Mt. Aconcagua, rises to an elevation of about 6,962 m above sea level. The peak of Mt. Chimborazo in the Ecuadorean Andes is farther from the centre of the Earth than any other location on the Earth's surface. This is because of the equatorial bulge that results from the Earth's rotation. The world's highest volcanoes are in the Andes, including Ojos del Salado on the Chile-Argentina frontier which rises to 6,893 m  and over 50 other volcanoes that rise above 6,000 m.
The Andes can be divided into three sections as the Southern Andes in Argentina and Chile, the Central Andes including the Chilean and Peruvian cordilleras and parts of Bolivia and the Northern Andes in Venezuela, Colombia, and Ecuador that consists of two parallel ranges, the Cordillera Occidental and the Cordillera Oriental. In Colombia, north of its the border with Ecuador, the Andes split in three parallel ranges, the western, central, and eastern ranges. The eastern range of Colombia is the only one that extends to Venezuela. In the northern part of the Andes, the isolated Sierra Nevada de Santa Marta range is often considered to be part of the Andes.

Colosseum


     This is an amphitheatre which is also known as Amphitheatrum Flavium, built in the center of the city Rome, Italy shaping in an ellipse. It is also the largest ever built in Roman Empire. Its construction began in 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign. Colosseum accommodates seating for 50,000 spectators which was basically used for  gladiatorial contests and public events such as mock sea battles, animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, and quarters for a religious order, a fortress, a quarry, and a Christian shrine.
It has been long believed that the name Colosseum was from a colossal statue of Nero nearby. This statue was later remodeled by Nero's successors into the likeness of Helios or Apollo, the sun god, by adding the appropriate solar crown. Nero's head was also replaced several times with the heads of succeeding emperors. Despite its pagan links, the statue remained standing well into the medieval era and was credited with magical powers. It came to be seen as an iconic symbol of the permanence of Rome. In the 8th century, a famous epigram attributed to the Venerable Bede celebrated the symbolic significance of the statue in a prophecy "as long as the Colossus stands, so shall Rome; when the Colossus falls, Rome shall fall; when Rome falls, so falls the world.” This is often mistranslated to refer to the Colosseum rather than the Colossus. The Colossus did eventually fall, possibly being pulled down to reuse its bronze.

Mariana Trench


Just as we have craters on our land masses, oceans too have such trenches. Though there are bit difficult to be visited by most of us, Mariana Trench is a should know place because it is the deepest trench in oceans of the world. Mariana trench is located in the western Pacific Ocean, to the east of the Mariana Islands. Amazingly it is about 2,550 kilometres (1,580 mi) long but has a mean width of only 69 kilometres (43 mi). It reaches a maximum-known depth of about 10.91 kilometres (6.78 mi) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end; although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi). If Mount Everest, the highest mountain on Earth at 8,850 metres (29,040 ft), was set in the deepest part of the Mariana Trench, there would be 2,060 metres (6,760 ft) of water left above it. So think how deep is that????

Giant's Causeway


      Located in County Antrim on the northeast coast of Northern Ireland, about three miles, Giant’s Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption.  Its tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven and eight sides. The tallest are about 12 metres (39 ft) high, and the solidified lava in the cliffs is 28 metres thick in places.
The Antrim was subject to intense volcanic activity, when highly fluid molten basalt intruded through chalk beds to form an extensive lava plateau during the Paleogene period. It was around some 50 to 60 million years ago.  Due to rapid cooling of Lava, contraction occurred and while contraction in the vertical direction reduced the flow thickness, horizontal contraction could only be accommodated by cracking throughout the flow. The size of the columns is basically determined by the speed at which lava from a volcanic eruption cools. The extensive fracture network produced the distinctive columns seen today. The basalts were originally part of a great volcanic plateau called the Thulean Plateau which formed during the Paleogene period.

Cathedral–Mosque of Córdoba


Located in the Andalusian city of Córdoba, Spain, is the former Great Mosque of Córdoba or the Catedral de Nuestra Señora de la Asunción which in English means the Cathedral of Our Lady of the Assumption. Before the Umayyad Moors converted the building into a mosque and then built a new mosque here, it was originally a pagan temple and then a Visigothic Christian church. After the Spanish Reconquista, it once again became a Roman Catholic Church, with a plateresque cathedral later inserted into the centre of the large Moorish building. The Mezquita is regarded as the one of the most accomplished monuments of Islamic architecture. 
The building was begun around the year 600 as the Christian Visigothic church of St. Vincent. After the Islamic conquest of the Visigothic kingdom, the church was divided between the Muslims and Christians. When the exiled Umayyad prince Abd ar-Rahman I escaped to Spain and defeated the Andalusian governor Yusuf al-Fihri, he allowed the Christians to rebuild their ruined churches, and purchased the Christian half of the church of St. Vincent. Abd ar-Rahman I and his descendants reworked it over two centuries to refashion it as a mosque, starting in 784. Additionally, Abd ar-Rahman I used the mosque as an adjunct to his palace and named it to honor his wife. Traditionally, the mihrab of a mosque faces in the direction of Mecca; by facing the mihrab, worshipers pray towards Mecca. Mecca is in east which means southeast of the mosque, but the mihrab points south. 

Yellowstone National Park


    This is a national park located in the U.S. state of Wyoming, although it also extends into Montana and Idaho. Yellowstone was the first national park in the world, and is very well famous for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular features in the park. It has many types of ecosystems, but the subalpine forest is dominant. It is believed Native Americans have lived in the Yellowstone region for at least 11,000 years. The region was bypassed during the Lewis and Clark Expedition in the early 19th century.
The Park spans an area of 3,468.4 square miles (8,983 km2), with features like lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-altitude lakes in North America and is centered over the Yellowstone Caldera, the largest super volcano on the continent. The caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years. Half of the world's geothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining, nearly intact ecosystem in the Earth's northern temperate zone. Yellowstone Park is the largest and most famous mega fauna location in the Continental United States.

Potala Palace

    Located in Lhasa,Tibet Autonomous Region, China, Potala Palace was the chief residence of the Dalai Lama until the 14th Dalai Lama fled to Dharamsala, India, after an invasion and failed uprising in 1959. It was named after Mount Potala, the abode of Chenresig or Avalokitesvara. Construction of the palace started in 1645 by Lozang Gyatso, the Great Fifth Dalai Lama after one of his spiritual advisers, Konchog Chophel, pointed out that the site was ideal as a seat of government, situated as it is between Drepung and Seramonasteries and the old city of Lhasa. Today, the Potala Palace serves as a museum.

The building spreads over 400 metres east-west and 350 metres north-south, with sloping stone walls averaging 3 m. thick, and 5 m. thick at the base, and with copper poured into the foundations to help proof it against earthquakes. Thirteen stories of buildings containing over 1,000 rooms, 10,000 shrines and about 200,000 statues  soar 117 metres (384 ft) on top of Marpo Ri, the "Red Hill", rising more than 300 m in total above the valley floor. It is said that the three main hills of Lhasa represent the "Three Protectors of Tibet." Chokpori, just to the south of the Potala, is the soul-mountain (bla-ri) of Vajrapani, Pongwari that of Manjushri, and Marpori, the hill on which the Potala stands, represents Chenresig or Avalokiteshvara.

Moai


Monolithic human figures carved from rock on the Polynesian island of Easter Island together are called Moai. They were carved between the years 1250 and 1500. There are still half of the originals at Rano Raraku, the main moai quarry, but hundreds were transported from there and set on stone platforms called ahu around the island's perimeter. Almost all moai have overly large heads three-fifths the size of their bodies. The moai are chiefly the living faces (aringa ora) of deified ancestors. Altogether it is believed that there are 887 statues whose production and transportation is considered a remarkable creative and physical feat. The tallest moai erected, called Paro, was about 10 metres (33 ft) high and weighed 82 tons; the heaviest erected was a shorter but squatter moai at Ahu Tongariki, weighing 86 tons; and one unfinished sculpture, if completed, would have been approximately 21 metres (69 ft) tall with a weight of about 270 tons.
It is believed that these statues were carved by the Polynesian colonizers of the island. In addition to representing deceased ancestors, the moai, once they were erected on ahu, may also have been regarded as the embodiment of powerful living or former chiefs and important lineage status symbols. Completed statues were moved to ahu mostly on the coast, and then erected, sometimes with red stone cylinders (pukao) on their heads. Moai must have been extremely expensive to craft and transport; not only would the actual carving of each statue require effort and resources, but the finished product was then hauled to its final location and erected. The quarries in Rano Raraku appear to have been abandoned abruptly, with their working tools everywhere. In the nineteenth century, this led to a theory that the island was the remnant of a sunken continent and that most completed moai were under the sea. That idea has long been debunked but now it is thoroughly understood because, some statues were rock carvings and never intended to be completed and some were incomplete because, when inclusions were encountered, the carvers would abandon a partial statue and start a new one. 

Hagia Sophia


It is a former mosque and now a museum found in Istanbul, Turkey which served as the Greek Patriarchal cathedral of Constantinople, except between 1204 and 1261, when it was converted to a Roman Catholic cathedral under the Latin Patriarch of Constantinople of the Western Crusader established Latin Empire. The building was a mosque from 29 May 1453 until 1931, when it was secularized. It was opened as a museum on 1 February 1935. The Church was dedicated to the Logos, the second person of the Holy Trinity, its dedication feast taking place on 25 December, the anniversary of the Birth of the incarnation of the Logos in Christ. 
Incredibly famous for its massive dome, it is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture." It was the largest cathedral in the world for nearly a thousand years, until Seville Cathedral was completed in 1520. The current building was originally constructed as a church between 532 and 537 on the orders of the Byzantine Emperor Justinian and was the third Church of the Holy Wisdom to occupy the site, the previous two having both been destroyed by rioters. It was designed by the Greek scientists Isidore of Miletus, a physicist, and Anthemius of Tralles, a mathematician. It also contains a large collection of holy relics. 

Banaue Rice Terraces


Carved into the mountains of Ifugao in the Philippines by ancestors of the indigenous people, the Banaue Rice Terraces also known as Payew, are 2000-year old terraces known to be built with minimal equipment, largely by hand. The terraces are located approximately 1500 meters (5000 ft) above sea level and cover 10,360 square kilometers (about 4000 square miles) of mountainside. They are fed by an ancient irrigation system from the rainforests above the terraces. It is said that if the steps are put end to end it would encircle half the globe. Rice and vegetables are planted on the terraces by the people, although more and younger Ifugaos do not find farming appealing, often opting for the more lucrative hospitality industry generated by the Rice Terraces. The result is the gradual erosion of the characteristic "steps", which need constant reconstruction and care. In 2010 a further problem was drought, with the terraces drying up completely in March of that year.
Ifugao rice terraces were declared free from Genetically Modified Organism (GMO)in March, 2009. An event was organized in Dianara Viewpoint for this announcement where it was graced by Gov. Teodoro Baguilat, Mayor Lino Madchiw, Greenpeace campaigner for Southeast Asia Daniel Ocampo, and Cathy Untalan who was executive director of the Miss Earth Foundation. Before the announcement ceremonies, 3 Mumbakis performed an Alim, a tribal ritual to ask for blessings where an animal is offered to the gods.
Many terraces are found in the province of Ifugao and the Ifugao people have been its caretakers. Ifugao culture is basically woven around rice and the culture displays an elaborate array of rice culture feasts linked with agricultural rites from rice cultivation to rice consumption. Harvest season generally calls for thanksgiving feasts while the concluding harvest rites tungo or tungul (the day of rest) entail a strict taboo of any agricultural work. Partaking of the bayah (rice beer), rice cakes, and betel nut constitutes an indelible practice during the festivities and ritual activities.

Bali


Bali is one of the 33 provinces of Indonesia which is also an island located in the western most end of the Lesser Sunda Islands, lying between Java to the west and Lombok to the east. The island is home to most of Indonesia's small Hindu minority. In the 2000 census about 92.29% of Bali's population adhered to Balinese Hinduism while most of the remainder follow Islam. It is also the largest tourist destination in the country and is renowned for its highly developed arts, including traditional and modern dance, sculpture, painting, leather, metalworking, and music. 
The island lies 3.2 km (2 mi) east of Java whereas Bali and Java are separated by the Bali Strait. East to west, the island is approximately 153 km (95 mi) wide and spans approximately 112 km (69 mi) north to south; its land area is 5,632 km². Bali's highest is Mount Agung (3,142 m), known as the "mother mountain" which is an active volcano. Mountains range from centre to the eastern side, with Mount Agung the easternmost peak. Bali's volcanic nature has contributed to its fertility and its tall mountain ranges provide the high rainfall that supports the highly productive agriculture sector. South of the mountains is a broad, steadily descending area where most of Bali's large rice crop is grown. The northern side of the mountains slopes more steeply to the sea and is the main coffee producing area of the island, along with rice, vegetables and cattle. The longest river, Ayung River, flows approximately 75 km.
Surrounded by coral reefs,  Bali’s beaches in the south have white sand while those in the north and west have black sand. Bali has no major waterways, although the Ho River is navigable by small sampan boats. Black sand beaches between Pasut and Klatingdukuh are being developed for tourism, but apart from the seaside temple of Tanah Lot, they are not yet used for significant tourism. The largest city is the provincial capital, Denpasar, near the southern coast. Bali's second-largest city is the old colonial capital, Singaraja, which is located on the north coast. Other important cities include the beach resort, Kuta, which is practically part of Denpasar's urban area; and Ubud, which is north of Denpasar, and is known as the island's cultural centre.

Perito Moreno Glacier


This can be called one of the most important tourist attractions in the Argentine Patagonia located in the Los Glaciares National Park in the south west of Santa Cruz province, Argentina. The 250 km2 (97 sq mi) ice formation, and 30 km (19 mi) in length, is one of 48 glaciers fed by the Southern Patagonian Ice Field located in the Andes system shared with Chile. This ice field is supposed to be the world's third largest reserve of fresh water. This is one of the three Patagonian glaciers that is growing and Theterminus of the Perito Moreno Glacier is 5 kilometres (3 mi) wide, with an average height of 74 m (240 ft) above the surface of the water of Lake Argentino, in Argentina. It has a total ice depth of 170 metres (558 ft).
The glacier first ruptured in 1917, taking with it an ancient forest of arrayán (Luma apiculata) trees. The last rupture occurred in July 2008, and previously in 2006, 2004, 1988, 1984, 1980, 1977, 1975, 1972, 1970, 1966, 1963, 1960, 1956, 1953, 1952, 1947, 1940, 1934 and 1917. Periodically the glacier advances over the L-shaped "Lago Argentino" ("Argentine Lake") forming a natural dam which separates the two halves of the lake when it reaches the opposite shore. The water-level on the Brazo Rico side of the lake can rise by up to 30 meters above the level of the main lake. The enormous pressure produced by the height of the dammed water finally breaks the ice barrier holding it back, in a spectacular rupture event. 

Yangshuo County


Yangshuo County is found in Guilin, Guangxi Province, China. It is located in Yangshuo Town. Surrounded by karst peaks and bordered on one side by the Li River, it has become a popular hot spot for foreign backpackers. Two main roads situated away from the water and form the central part of the town, Chinese Street Die Cui Lu and West Street Xi Jie. 
There are plenty of activities to do around Yangshuo. Tourists and visitors can swim in the Li River or the cleaner Yu Long also known as the Dragon River. Or else you can climb one of many nearby karst peaks, hire a bicycle for a cycling trip through the karst scenery, arrange a sightseeing trip on the Li River by bamboo raft or cruise boat, or visit a number of local cave systems, including a butterfly cave. The mild climate is also good for health and such activities will make your body burn the extra unwanted calories. Yangshuo is also China's foremost venue for rock climbing, with around 300 bolted routes and several companies offering guiding and equipment hire.
Zhang Yimou's folk musical "Impression Liu Sanjie" is a popular extravaganza performed outdoors in a river and mountain setting with a cast of 600 singers and dancers. Basically most of the town’s traditional culture has been devoted to the tourist industry, and tourists can pay a fee to watch fishermen fishing with cormorants, hire local women in traditional ethnic dress to pose for photographs, or take classes in Chinese calligraphy, tea ceremony, or cooking.

Carlsbad Caverns National Park

 It is a United States National Park in the Guadalupe Mountains in southeastern New Mexico. The park consist of the show cave, Carlsbad Caverns where people who come to visit the cave can hike in on their own via the natural entrance, or take the elevator (the exit for everyone) directly to the Underground Lunchroom some 750 feet (230 m) below. The park has two entries on the National Register of Historic Places: The Caverns Historic District and the Rattlesnake Springs Historic District. Approximately two thirds of the park has been set aside as a wilderness area, helping to ensure no future changes will be made to the habitat. Carlsbad Caverns consist of a large cave chamber, the Big Room, a natural limestone chamber which is almost 4,000 feet (1,220 m) long, 625 feet (191 m) wide, and 350 feet (110 m) high at the highest point. It is the third largest chamber in North America and the seventh largest in the world. The largest in the world is the Sarawak Chamber in Malaysia.
From a young age, Jim White explored the caverns with his homemade wire ladder. When he grew older, most people did not even believe such caves existed. He gave many of the rooms their names, including the Big Room, New Mexico Room, King's Palace, Queen's Chamber, Papoose Room, and Green Lake Room. He also named many of the cave's more prominent formations, such as the Totem Pole, Witch's Finger, Giant Dome, Bottomless Pit, Fairyland, Iceberg Rock, Temple of the Sun, and Rock of Ages.
The town of Carlsbad, which lends its name to the Caverns and National Park, is in turn named after the Czech town formerly known by the German name Karlsbad and now known by the Czech name Karlovy Vary, both of which mean "Charles' Bath." Until 1932, visitors to the cavern had to walk down a switch back ramp-sidewalk that took them 750 feet below the surface. The walk back up was hard on a lot of visitors. In 1932 the National Park opened up a large visitor center building that contained two elevators that would take visitors to the caverns below. The new center included a cafeteria, waiting room, museum and first aid area. 

Galápagos Islands


    They are an archipelago of volcanic islands scattered around the equator in the Pacific Ocean. Part of continental Ecuador lying 972 km (525 nmi) west of it, Galapagos Islands are geologically young and home for various number of endemic species.  Observations on these species lead to the rise of theories like the inception of Darwin's theory of evolution by natural selection. The exact location is found in the eastern Pacific Ocean, 973 km (525 nmi; 605 mi) off the west coast of South America. The closest is the mainland of Ecuador to the east, to the north is Cocos Island at 720 km (389 nmi; 447 mi) and to the south is Easter Island and San Felix Island at 3,200 km (1,730 nmi; 1,990 mi).
The Galápagos Archipelago consists of 7,880 km2 (3,040 sq mi) of land spread over 45,000 km2 (17,000 sq mi) of ocean. The largest of the islands, Isabela, measures 4,640 km2 (1,790 sq mi) and makes up half of the total land area of the Galápagos. Volcán Wolf on Isabela is the highest point, with an elevation of 1,707 m (5,600 ft) above sea level. The island chain consists of 15 main islands, 3 smaller islands, and 107 rocks and islets. The archipelago is located on the Nazca tectonic plate, which is moving east/southeast, diving under the South American Plate at a rate of about 2.5 inches per year. It is also atop the Galapagos hotspot, a place where the Earth's crust is being melted from below by a mantle plume, creating volcanoes. The oldest island is thought to have formed between 5 million and 10 million years ago. The youngest islands, Isabela and Fernandina, are still being formed, with the most recent volcanic eruption in April 2009, where lava from the volcanic island Fernandina started flowing both towards the island's shoreline and into the centre caldera.

Ngorongoro Conservation Area


Ngorongoro is a conservation site found in Tanzania, with various attractions and natural creations such as Ngorongoro crater, Olduvai Gorge and many flora and fauna.  Based on fossil evidence, the area was home to many hominid species for 3 million years. Hunter-gatherers were replaced by pastorialists a few thousand years ago. The Mbulu came to the area about 2,000 years ago, and were joined by the Datooga around the year 1700. Both groups were driven from the area by the Maasai in the 1800s. Massive fig trees in the northwest of the Lerai Forest are sacred to the Maasai and Datooga people. Some of them may have been planted on the grave of a Datago leader who died in battle with the Maasai around 1840.
The Ngorongoro area originally was part of the Serengeti National Park when it was created by the British in 1951. Maasai continued to live in the newly created park until 1959, when repeated conflicts with park authorities over land use led the British to evict them to the newly declared Ngorongoro Conservation Area. Ngorongoro area is supposed to be the only place that provides protection for wild life as well as that allows human habitation. Anyhow several limitations are posed in order to protect wild life such as prohibition of cultivation except at subsistence levels. 
The area is part of the Serengeti ecosystem, and to the north-west, it adjoins the Serengeti National Park and is contiguous with the southern Serengeti plains, these plains also extend to the north into unprotected Loliondo division and are kept open to wildlife through trans-human pastoralism practiced by Maasai. The south and west of the area are volcanic highlands, including the famous Ngorongoro Crater and the lesser known Empakai. The southern and eastern boundaries are approximately defined by the rim of the Great Rift Valley wall, which also prevents animal migration in these directions. 

White Immensity of Antarctica


  What is so beautiful about a land completely covered by ice??? Well, beauty lies in different forms in different places. Antarctica is the ice cover we find near South Pole. It is a permanently frozen ground surrounded by water, and is about 1 1/2 times larger than the United States. The world’s largest desert is on Antarctica. 98 percent of the land is covered with a continental ice sheet; the remaining 2 percent of land is barren rock. Antarctica has about 87% of the world’s ice. 
The South Pole is the coldest, windiest, and driest place on Earth. On average, most of Antarctica gets less than 2 inches of snow fall each year. Antarctica is a fast developing tourist attraction. There is now ample opportunity to ascend Mount Erebus, the southernmost active volcano on Earth; to fly via helicopter or venture by boat to penguin colonies; and to really make the most of a terrain that teems with wildlife, with a multitude of birds, seals, albatrosses and enormous whales; and so on.
Another wonderful sight you can experience here is its wild life. Although there are only a few native species, those that have adapted to the harsh environment thrive in large numbers. Penguin populations are counted in the tens of thousands in some rookeries.
If you plan to go on a trip, spend time visiting the Antarctic Peninsula, Falkland Islands and the mountainous South Georgia. Antarctica cruises offer zodiac excursions for up-close encounters with wildlife and the blue icebergs that float quietly in the surrounding waters. You can experience Antarctic kayaking or onshore camping. On Antarctica tours, onboard experts lecture on the region's natural history, weather, and captivating wildlife commonly seen during a cruise to the frozen continent.

Angkor City


Being the largest preindustrial city in the world, with an elaborate system of infrastructure connecting an urban sprawl of at least 1,000 square kilometres (390 sq mi) to the well-known temples at its core, Angkor city in Cambodia served as the Khmer Empire from 9th to 15th centuries. The temples of the Angkor area number over one thousand, ranging in scale from nondescript piles of brick rubble scattered through rice fields to the magnificent Angkor Wat, said to be the world's largest single religious monument. Many of the temples at Angkor have been restored, and together, they comprise the most significant site of Khmer architecture.
The Angkorian period began in AD 802, when the Khmer Hindu monarch Jayavarman II declared himself a "universal monarch" and "god-king", until 1351, when Angkor first fell under Ayutthayan suzainry, to 1431, when Ayutthaya put down a rebellion and sacked the Khmer capital, causing its population to migrate south to the area of Phnom Penh. In 889, Yasovarman took over the throne who was a great ruler. He built a new city known as Yasodharapura and a new reservoir called Baray.  
Over the next 300 years, between 900 and 1200, the Khmer Empire produced some of the world's most magnificent architectural masterpieces in the area known as Angkor. Most are concentrated in an area approximately 15 miles (24 km) east to west and 5 miles (8.0 km) north to south, although the Angkor Archaeological Park, which administers the area, includes sites as far away as Kbal Spean, about 30 miles (48 km) to the north. Some 72 major temples or other buildings are found within this area, and the remains of several hundred additional minor temple sites are scattered throughout the landscape beyond. Because of the dispersed, low-density nature of the medieval Khmer settlement pattern, Angkor lacks a formal boundary, and its extent is therefore difficult to determine. However, a specific area of at least 1,000 km2 (390 sq mi) beyond the major temples is defined by a complex system of infrastructure, including roads and canals that indicate a high degree of connectivity and functional integration with the urban core. In terms of spatial extent, this makes it the largest urban agglomeration in human history prior to the Industrial Revolution, easily surpassing the nearest claim, that of the Mayan city of Tikal. In fact, in terms of its urban sprawl, medieval Angkor even approaches the size of modern Los Angeles, and is said to have been seventeen times larger than Manhattan Island. 

City of Venice


It is suppose to be one of the world’s most romantic cities. With canals of water instead of roads and smiling people always ready to guide you through the city and the magnificent structures displaying eras’ worth of architecture and legends, Venice is a number one choice in Europe for anyone. The name is derived from the ancient Veneti people who inhabited the region by the 10th century B.C. The city historically was the capital of the Venetian Republic. Venice has been known as the "La Dominante", "Serenissima", "Queen of the Adriatic", "City of Water", "City of Masks", "City of Bridges", "The Floating City", and "City of Canals".  The city stretches across 117 small islands in the marshy Venetian Lagoon along the Adriatic Sea in northeast Italy. The saltwater lagoon stretches along the shoreline between the mouths of the Po (south) and the Piave (north) Rivers. 
The classical Venetian boat is the gondola, although it is now mostly used for tourists, or for weddings, funerals, or other ceremonies. Many gondolas are lushly appointed with crushed velvet seats and Persian rugs. Less well-known is the smaller sandolo. The main transportation means are motorised waterbuses (vaporetti), which ply regular routes along the major canals and between the city's islands, and private boats. The only gondolas still in common use by Venetians are the traghetti, foot passenger ferries crossing the Grand Canal at certain points without bridges.
Azienda Consorzio Trasporti Veneziano (ACTV) is the name of the public transport system in Venice. It combines land transportation, with buses, and canal travel, with water buses (vaporetti). In total, there are 25 routes that connect the city. The Venice People Mover (managed by ASM) is a cable operated public transit system connecting Tronchetto Island with Piazzale Roma. Water taxis are also active. 

Trincomalee


Trincomalee is a district of the Eastern province of Sri Lanka best known for its maritime activities and natural harbor. Trincomalee originally scraped its name from Tamil giving the meaning “Lord of the sacred hill” and it lies on the east coast of the island, about 113 miles south of Jaffna. The Bay of Trincomalee harbour is renowned for its large size and security; unlike every other in the Indian Sea, it is accessible to all types of craft in all weathers. The beaches are used for surfing, scuba diving, fishing and whale watching. The city also has the largest Dutch fort in Sri Lanka. It is home to major Sri Lankan naval bases and a Sri Lankan Air Force base. 
Sanskrit texts, as well as an inscription unearthed by archeologists, call it Gokanna. The Vayu Purana refers to a Siva temple on Trikuta hill on the eastern coast of Lanka in the 3rd century. The Mahavamsa documents that the King Mahasena destroyed a Deva temple and built a Buddhist shrine in its stead to expiate for an earlier heresy on his part. Tamil texts, as well as excavated inscriptions detail the Saivite principalities that formed in Trincomalee in service of the Koneswaram temple by the medieval age. The South Indian Tamil literature Tevaram of Tiru-gnana Sambandar makes mention to the Siva temple in Trincomalee in the 6th century. Koneswaram and the royal administration of the city is documented in several late medieval texts such as the Konesar Kalvettu and the Dakshina Kailasa Puranam. 
Trincomalee features a tropical wet and dry climate under the Koppen climate classification. The city appears to feature a dry season from March through July and a wet season for the remainder of the year. Technically however, May which sees on average 70 mm of precipitation, is a wet season month. In essence, Trincomalee features two dry seasons. The city sees on average roughly 1650 mm of precipitation annually. Average temperatures in Trincomalee range from around 25 degrees Celsius in January to approximately 30 degrees Celsius during the warmest months of the year.

Hawaii Islands


Hawaii is the newest state of US and the only state completely made of islands. Hawaii’s natural and diverse scenery, warm tropical climate, abundance of public beaches and oceanic surrounding, and active volcanoes make it a popular destination for tourists, surfers, biologists, and volcanologists alike. Its capital is Honolulu on the island of Oʻahu. The state comprises hundreds of islands spread over 1,500 miles (2,400 km). At the southeastern end of the archipelago, the eight main islands are (from the northwest to southeast) Niʻihau, Kauaʻi,Oʻahu, Molokaʻi, Lānaʻi, Kahoʻolawe, Maui, and Hawai’i. The last is by far the largest and is often called "The Big Island" to avoid confusion with the state as a whole. The archipelago is physiographically and ethnologically part of the Polynesian sub region of Oceania. 
Hawaii means “homeland” in Hawaiian language. Talking about Hawaii and its nature, Hawaii’s tallest mountain, Mauna Kea, stands at 13,796 ft (4,205 m) but is taller than Mount Everest if followed to the base of the mountain, which, lying at the floor of the Pacific Ocean, rises about 33,500 ft(10,200 m). All the Hawaiian Islands were formed from volcanic activity initiated at an undersea magma source called a hotspot. As the tectonic plate beneath much of the Pacific Ocean moves to the northwest, the hot spot remains stationary, slowly creating new volcanoes. Due to the hotspot’s location, the only active volcanoes are located around the southern half of the Big Island. The newest volcano, Lōʻihi Seamount, is located south of the Big Island’s coast. The last volcanic eruption outside the Big Island occurred at Haleakalā on Maui before the late 18th century, though it could have been hundreds of years earlier. In 1790, Kīlauea exploded with the deadliest eruption (of the modern era) known to have occurred in what is now the United States. As many as 5,405 warriors and their families marching on Kīlauea were killed by that eruption. Volcanic activity and subsequent erosion have created impressive geological features. The Big Island has the third highest point among the world’s islands. 

Eiffel Tower


Once the tallest structure in the world, Eiffel Tower has been the iconic symbol for Paris and to the France.  It was built in 1889 as a puddle iron lattice tower standing magnificently above all. The tower is the tallest building in Paris and the most-visited paid monument in the world; millions of people ascend it every year. Named after its designer, engineer Gustave Eiffel, the tower was built as the entrance arch to the 1889 World's Fair. The tower stands 324 metres (1,063 ft) tall, about the same height as an 81-storey building. The tower has three levels for visitors. Tickets can be purchased to ascend, by stairs or lift, to the first and second levels. The walk from ground level to the first level is over 300 steps, as is the walk from the first to the second level. The third and highest level is accessible only by elevator. Both the first and second levels feature restaurants.
Three hundred workers joined together 18,038 pieces of puddle iron (a very pure form of structural iron), using two and a half million rivets, in a structural design by Maurice Koechlin. Eiffel was assisted in the design by engineers Émile Nouguier and Maurice Koechlin and architect Stephen Sauvestre. The risk of accident was great as, unlike modern skyscrapers, the tower is an open frame without any intermediate floors except the two platforms. However, because Eiffel took safety precautions, including the use of movable stagings, guard-rails and screens, only one man died. The tower was inaugurated on 31 March 1889, and opened on 6 May. Eiffel had a permit for the tower to stand for 20 years; it was to be dismantled in 1909, when its ownership would revert to the City of Paris. The City had planned to tear it down (part of the original contest rules for designing a tower was that it could be easily demolished) but as the tower proved valuable for communication purposes, it was allowed to remain after the expiry of the permit. The military used it to dispatch Parisian taxis to the front line during the First Battle of the Marne.
The pig iron structure of the Eiffel Tower weighs 7,300 tonnes while the entire structure, including non-metal components, is approximately 10,000 tonnes. As a demonstration of the economy of design, if the 7,300 tonnes of the metal structure were melted down it would fill the 125 metre square base to a depth of only 6 cm (2.36 in), assuming the density of the metal to be 7.8 tonnes per cubic metre. Depending on the ambient temperature, the top of the tower may shift away from the sun by up to 18 cm (7.1 in) because of thermal expansion of the metal on the side facing the sun. Researchers have found that Eiffel used empirical and graphical methods accounting for the effects of wind rather than a specific mathematical formula. Careful examination of the tower shows a basically exponential shape; actually two different exponentials, the lower section overdesigned to ensure resistance to wind forces. Several mathematical explanations have been proposed over the years for the success of the design; the most recent is described as a nonlinear integral equation based on counterbalancing the wind pressure on any point on the tower with the tension between the construction elements at that point. As a demonstration of the tower's effectiveness in wind resistance, it sways only 6–7 cm (2–3 in) in the wind.

Teotihuacan

 Teotihuacan stands for "The City of the Gods" in the Nahuatl language of the Aztecs. It is an archeological site found in the basin of Mexico containing large pyramidal structures, large residential complexes, Avenue of the Dead, and numerous colorful, well-preserved murals. Additionally, Teotihuacan produced a thin orange pottery style that spread through Mesoamerica.  At its zenith, perhaps in the first half of the 1st millennium CE, Teotihuacan was the largest city in the pre-Columbian Americas. At this time it may have had more than 200,000 inhabitants, placing it among the largest cities of the world in this period. Teotihuacan was even home to multi-floor apartment compounds built to accommodate this large population. The civilization and cultural complex associated with the site is also referred to as Teotihuacan or Teotihuacano.
The city and the archaeological site are located in what is now the San Juan Teotihuacán municipality in the State of México, Mexico, approximately 40 kilometres (25 mi) northeast of Mexico City. The site covers a total surface area of 83 km² and was designated a UNESCO World Heritage Site in 1987. It is the most visited archaeological site in Mexico.
For many years, archaeologists believed it was built by the Toltec. This belief was based on colonial period texts, such as the Florentine Codex, which attributed the site to the Toltecs. However, the Nahuatl word "Toltec" generally means "craftsman of the highest level" and may not always refer to the Toltec civilization centered at Tula, Hidalgo. Since Toltec civilization flourished centuries after Teotihuacan, the people could not have been the city's founders. In the Late Formative period, a number of urban centers arose in central Mexico. The most prominent of these appears to have been Cuicuilco, on the southern shore of Lake Texcoco. Some believed that the eruption of the Xitle volcano may have prompted a mass emigration out of the central valley and into the Teotihuacan valley. These settlers may have founded and/or accelerated the growth of Teotihuacan. Some have put forth the Totonac people as the founders of Teotihuacan. There is evidence that at least some of the people living in Teotihuacan came from areas influenced by the Teotihuacano civilization, including the Zapotec, Mixtec and Maya peoples. The culture and architecture of Teotihuacan was influenced by the Olmec people, who are considered to be the "mother civilization" of Mesoamerica. The earliest buildings at Teotihuacan date to about 200 BCE. The largest pyramid, the Pyramid of the Sun, was completed by 100 CE.

Preikestolen


Preikestolen cliff has become a very famous tourist destination today. Preikestolen also known as the Pulpit rock is a cliff of height about 604 metres above Lysefjorden, opposite the Kjeragplateau, in Forsand, Ryfylke, Norway. The top of the cliff is approximately 25 by 25 metres (82 by 82 feet) square, almost flat. The Pulpit Rock is located in Rogaland, a county in Western Norway. The city of Stavanger, the fourth largest in Norway, is located only 25 kilometers from the site, and the parking facility of the Pulpit Rock is located about one hour from Stavanger by ferry and car.
The cliff was formed during the Ice age, about approximately 10,000 years ago, when the edges of the glacier reached the cliff. The water from the glacier froze in the crevices of the mountain and eventually broke off large, angular blocks, which were later carried away with the glacier. This is the cause of the angular shape of the plateau. Along the plateau itself there continues to be a deep crack. Geologists of the region, however, confirm the safety of the plateau. 
What is unique with this place is as the name indicates; this looks like a pulpit when seen from below. The rock itself is like 25 by 25 meters and when you stand on the edge it is 600 meters straight down. And on clear days you get a great view of the Lysefjord. The path leading up to Preikestolen is also very scenic - especially the last part when you start getting the first glimpse of the Lyse fjord.
There was a big debate a few years ago in the local community by the way. Some people suggested that a pier should be constructed in Lysefjord and a lift should be built from the fjord to the Pulpit rock. This would have attracted quite a lot of cruise ships to the Stavanger area but on the other hand it would have spoiled some of the experience.
