PETRA (JORDAN)

Petra ("petra-πέτρα", cleft in the rock in Greek; Arabic: البتراء, Al-Batrāʾ) is an archaeological site in the Arabah, Ma'an Governorate, Jordan, lying on the slope of Mount Hor[1] in a basin among the mountains which form the eastern flank of Arabah (Wadi Araba), the large valley running from the Dead Sea to the Gulf of Aqaba. It is renowned for its rock-cut architecture. Petra is also one of the new wonders of the world. The Nabateans constructed it as their capital city around 100 BC.[2]
The site remained unknown to the Western world until 1812, when it was introduced to the West by Swiss explorer Johann Ludwig Burckhardt. It was famously described as "a rose-red city half as old as time" in a Newdigate prize-winning sonnet by John William Burgon. UNESCO has described it as "one of the most precious cultural properties of man's cultural heritage."[3] In 1985, Petra was designated a World Heritage Site.

MACHU PICCHU

Machu Picchu (Quechua: Machu Pikchu, "Old Peak", pronounced [ˈmɑtʃu ˈpiktʃu]) is a pre-Columbian Inca site located 2,430 metres (8,000 ft) above sea level[1]. It is situated on a mountain ridge above the Urubamba Valley in Peru, which is 80 kilometres (50 mi) northwest of Cuzco and through which the Urubamba River flows. Often referred to as "The Lost City of the Incas", Machu Picchu is one of the most familiar symbols of the Inca Empire.
The Incas started building it around AD 1430 but was abandoned as an official site for the Inca rulers a hundred years later at the time of the Spanish conquest of the Inca Empire. Although known locally, it was largely unknown to the outside world before being brought to international attention in 1911 by Hiram Bingham, an American historian. Since then, Machu Picchu has become an important tourist attraction.
Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. Since it was not plundered by the Spanish when they conquered the Incas, it is especially important as a cultural site and is considered a sacred place.
Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its primary buildings are the Intihuatana, the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu. In September 2007, Peru and Yale University reached an agreement regarding the return of artifacts which Hiram Bingham had removed from Machu Picchu in the early twentieth century.

CHICHEN ITZA

Chichen from Yucatec Maya "At the mouth of the well of the Itza") is a large pre-Columbian archaeological site built by the Maya civilization located in the northern center of the Yucatán Peninsula, in the Yucatán state, present-day Mexico.
Chichen Itza was a major regional focal point in the northern Maya lowlands from the Late Classic through the Terminal Classic and into the early portion of the Early Postclassic period. The site exhibits a multitude of architectural styles, from what is called “Mexicanized” and reminiscent of styles seen in central Mexico to the Puuc style found among the Puuc Maya of the northern lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.
The ruins of Chichen Itza are federal property, and the site’s stewardship is maintained by Mexico’s Instituto Nacional de Antropología e Historia (National Institute of Anthropology and History, INAH). The land under the monuments, however, is privately-owned by the Barbachano family.[3]
Northern Yucatán is arid, and the interior has no above-ground rivers. There are two large, natural sink holes, called cenotes, that could have provided plentiful water year round at Chichen, making it attractive for settlement. Of the two cenotes, the "Cenote Sagrado" or Sacred Cenote (also variously known as the Sacred Well or Well of Sacrifice), is the more famous. According to post-Conquest sources (Maya and Spanish), pre-Columbian Maya sacrificed objects and human beings into the cenote as a form of worship to the Maya rain god Chaac. Edward Herbert Thompson dredged the Cenote Sagrado from 1904 to 1910, and recovered artifacts of gold, jade, pottery, and incense, as well as human remains.[7] A recent study of human remains taken from the Cenote Sagrado found that they had wounds consistent with human sacrifice.

TAJ MAHAL

The Taj Mahal is a mausoleum located in Agra, India, built by Mughal Emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal.
The Taj Mahal (also "the Taj") is considered the finest example of Mughal architecture, a style that combines elements from Persian, Indian, and Islamic architectural styles.[1][2] In 1983, the Taj Mahal became a UNESCO World Heritage Site and was cited as "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage."
While the white domed marble mausoleum is its most familiar component, the Taj Mahal is actually an integrated complex of structures. Building began around 1632 and was completed around 1653, and employed thousands of artisans and craftsmen.[3] The construction of the Taj Mahal was entrusted to a board of architects under imperial supervision including Abd ul-Karim Ma'mur Khan, Makramat Khan, and Ustad Ahmad Lahauri.[4][5] Lahauri is generally considered to be the principal designer.[6]

The Taj Mahal was built on a parcel of land to the south of the walled city of Agra. Shah Jahan presented Maharajah Jai Singh with a large palace in the center of Agra in exchange for the land.[24] An area of roughly three acres was excavated, filled with dirt to reduce seepage, and leveled at 50 meters above riverbank. In the tomb area, wells were dug and filled with stone and rubble to form the footings of the tomb. Instead of lashed bamboo, workmen constructed a colossal brick scaffold that mirrored the tomb. The scaffold was so enormous that foremen estimated it would take years to dismantle. According to the legend, Shah Jahan decreed that anyone could keep the bricks taken from the scaffold, and thus it was dismantled by peasants overnight. A fifteen kilometer tamped-earth ramp was built to transport marble and materials to the construction site and teams of twenty or thirty oxen pulled the blocks on specially constructed wagons. An elaborate post-and-beam pulley system was used to raise the blocks into desired position. Water was drawn from the river by a series of purs, an animal-powered rope and bucket mechanism, into a large storage tank and raised to a large distribution tank. It was passed into three subsidiary tanks, from which it was piped to the complex

COLOSSEUM ITALY

The Colosseum or Roman Coliseum, originally the Flavian Amphitheatre (Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio or Colosseo), is an elliptical amphitheatre in the center of the city of Rome, Italy, the largest ever built in the Roman Empire. It is one of the greatest works of Roman architecture and Roman engineering.
Occupying a site just east of the Roman Forum, its construction started between 70 and 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications being made during Domitian's reign (81–96).[1] The name "Amphitheatrum Flavium" derives from both Vespasian's and Titus's family name (Flavius, from the gens Flavia).
Capable of seating 50,000 spectators,[2] the Colosseum was used for gladiatorial contests and public spectacles. As well as the gladiatorial games, other public spectacles were held there, 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, quarters for a religious order, a fortress, a quarry, and a Christian shrine.
It has been estimated that about 500,000 people and over a million wild animals died in the Colosseum games.[3][4]
Although in the 21st century it stays partially ruined due to damage caused by devastating earthquakes and stone-robbers, the Colosseum is an iconic symbol of Imperial Rome and its breakthrough achievements in earthquake engineering. It is one of Rome's most popular tourist attractions and still has close connections with the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession around the various levels of the amphitheatre.[5]

GREAT WALL OF CHINA

The Great Wall of China (simplified Chinese: 长城; traditional Chinese: 長城; pinyin: Chángchéng; literally "long city/fortress") or (simplified Chinese: 万里长城; traditional Chinese: 萬里長城; pinyin: Wànlǐ Chángchéng; literally "The long wall of 10,000 Li (里)"[1]) is a series of stone and earthen fortifications in northern China, built, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire from Xiongnu attacks during various successive dynasties. Since the 5th century BC, several walls have been built that were referred to as the Great Wall. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang. Little of that wall remains; it lay farther north than the current wall, which was built during the Ming Dynasty.[2]
The Great Wall stretches over approximately 6,400 km (4,000 miles)[3] from Shanhaiguan in the east to Lop Nur in the west, along an arc that roughly delineates the southern edge of Inner Mongolia, but stretches to over 6,700 km (4,160 miles) in total;[4] a more recent archaeological survey using advanced technologies points out that the entire Great Wall, with all of its branches, stretches for 8,851.8 km (5,500.3 mi).[5][6][7] At its peak, the Ming Wall was guarded by more than one million men.[8] It has been estimated that somewhere in the range of 2 to 3 million Chinese died as part of the centuries-long project of building the wall.

Before the use of bricks, the Great Wall was mainly built from Earth or Taipa, stones, and wood.
During the Ming Dynasty, however, bricks were heavily used in many areas of the wall, as were materials such as tiles, lime, and stone. The size and weight of the bricks made them easier to work with than earth and stone, so construction quickened. Additionally, bricks could bear more weight and endure better than rammed earth. Stone can hold under its own weight better than brick, but is more difficult to use. Consequently, stones cut in rectangular shapes were used for the foundation, inner and outer brims, and gateways of the wall. Battlements line the uppermost portion of the vast majority of the wall, with defensive gaps a little over 30 cm (one foot) tall, and about 23 cm (9 inches) wide.

CHRIST THE REDEEMER (statue)

The idea for erecting a large statue atop Corcovado was first suggested in the mid 1850s, when Catholic priest Pedro Maria Boss requested financing from Princess Isabel to build a large religious monument. Princess Isabel did not think much of the idea and it was completely dismissed in 1889, when Brazil became a Republic, with laws mandating the separation of church and state.[6] The second proposal for a large landmark statue on the mountain was made in 1921 by the Catholic Circle of Rio.[7] The group organised an event called Semana do Monumento ("Monument Week") to attract donations and collect signatures to support the building of the statue. The donations came mostly from Brazilian Catholics.[1] The designs considered for the "Statue of the Christ" included a representation of the Christian cross, a statue of Jesus with a globe in his hands, and a pedestal symbolizing the world.[8] The statue of Christ the Redeemer with open arms was chosen.
Local engineer Heitor da Silva Costa designed the statue; it was sculpted by French sculptor Paul Landowski.[1][9] A group of engineers and technicians studied Landowski's submissions and the decision was made to build the structure out of reinforced concrete (designed by Albert Caquot) instead of steel, more suitable for the cross-shaped statue.[6] The outer layers are soapstone, chosen for its enduring qualities and ease of use.[4] Construction took nine years, from 1922 to 1931. The monument was opened on October 12, 1931.[4][5] The cost of the monument was $250,000. The statue was meant to be lit by a battery of floodlights triggered remotely by shortwave radio pioneer Guglielmo Marconi, stationed 5,700 miles (9,200 km) away in Rome[7], but poor weather affected the signal and it had to be lit by workers in Rio.[6]
The statue was struck by lightning during a violent electrical storm on Sunday, February 10, 2008. The storm caused havoc in Rio, felling trees in several neighborhoods, but the statue was left unscathed because soapstone, the material forming the outer layers of the statue, is an insulator.[10][11] In October 2006, on the statue's 75th anniversary, Archbishop of Rio Cardinal Eusebio Oscar Scheid consecrated a chapel (named for the patron saint of Brazil - Nossa Senhora Aparecida) under the statue. This allows Catholics to hold baptisms and weddings there.[5]

GREAT PYRAMID OF GIZA

The Great Pyramid of Giza (also called the Khufu's Pyramid, Pyramid of Khufu, and Pyramid of Cheops) is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now Cairo, Egypt, and is the only one of the Seven Wonders of the Ancient World that survives substantially intact. It is believed the pyramid was built as a tomb for Fourth dynasty Egyptian King Khufu (Cheops in Greek) and constructed over a 20 year period concluding around 2560 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Originally the Great Pyramid was covered by casing stones that formed a smooth outer surface, and what is seen today is the underlying core structure. Some of the casing stones that once covered the structure can still be seen around the base. There have been varying scientific and alternative theories regarding the Great Pyramid's construction techniques. Most accepted construction theories are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.
There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The so-called[1] Queen's Chamber and King's Chamber are higher up within the pyramid structure. The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.
