Chichen itza pyramid

Chichen itza pyramid 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 pyramid 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.
chichen itza pyramid History
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. A recent study of human remains taken from the Cenote Sagrado found that they had wounds consistent with human sacrifice.

Great wall of China

TheGreat wall of china of 10,000 is a series of stone and earthen fortifications in 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 the rule of successive dynasties. Several walls, referred to as the Great Wall of China, were built since the 5th century BC. One of the most famous is the wall built between 220–206 BC by the first Emperor of China, Qin Shi Huang; little of it remains; it was much farther north than the current wall, which was built during the Ming Dynasty.
great wall of china stretches over approximately 6,400 km (4,000 miles) 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. At its peak, the Ming Wall was guarded by more than one million men. 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 great wall of china.

History
The Chinese were already familiar with the techniques of wall-building by the time of the Spring and Autumn Period, which began around the 8th century BC. During the Warring States Period from the 5th century BC to 221 BC, the states of Qi, Yan and Zhao all constructed extensive fortifications to defend their own borders. Built to withstand the attack of small arms such as swords and spears, these walls were made mostly by stamping earth and gravel between board frames. Qin Shi Huang conquered all opposing states and unified China in 221 BC, establishing the Qin Dynasty. Intending to impose centralized rule and prevent the resurgence of feudal lords, he ordered the destruction of the wall sections that divided his empire along the former state borders. To protect the empire against intrusions by the Xiongnu people from the north, he ordered the building of a new wall to connect the remaining fortifications along the empire's new northern frontier. Transporting the large quantity of materials required for construction was difficult, so builders always tried to use local resources. Stones from the mountains were used over mountain ranges, while rammed earth was used for construction in the plains. There are no surviving historical records indicating the exact length and course of the Qin Dynasty walls. Most of the ancient walls have eroded away over the centuries, and very few sections remain today. Later, the Han, Sui, Northern and Jin dynasties all repaired, rebuilt, or expanded sections of the great wall of china at great cost to defend themselves against northern invaders.The great wall of chinal concept was revived again during the Ming Dynasty following the Ming army's defeat by the Oirats in the Battle of Tumu in 1449. The Ming had failed to gain a clear upper-hand over the Manchurian and Mongolian tribes after successive battles, and the long-drawn conflict was taking a toll on the empire. The Ming adopted a new strategy to keep the nomadic tribes out by constructing walls along the northern border of China. Acknowledging the Mongol control established in the Ordos Desert, the wall followed the desert's southern edge instead of incorporating the bend of the Huang He. Photograph of the Great Wall in 1907Unlike the earlier Qin fortifications, the Ming construction was stronger and more elaborate due to the use of bricks and stone instead of rammed earth. As Mongol raids continued periodically over the years, the Ming devoted considerable resources to repair and reinforce the great wall of china. Sections near the Ming capital of Beijing were especially strong.During 1440s-1460s, the Ming also built a so-called "Liaodong Wall". Similar in function to the Great Wall (whose extension it, in a sense, was), but more basic in construction, the Liaodong Wall enclosed theagricultural heartland of the Liaodong province, protecting it potential incursions by Jurched-Mongol Oriyanghan from the northwest and the Jianzhou Jurchens from the north. While stones and tiles were used in some parts of the Liaodong Wall, most of it was in fact simply an earth dike with moats on both sides.Towards the end of the Ming Dynasty, thegreat wall of china helped defend the empire against the Manchu invasions that began around 1600. Under the military command of Yuan Chonghuan, the Ming army held off the Manchus at the heavily fortified Shanhaiguan pass, preventing the Manchus from entering the Chinese heartland. The Manchus were finally able to cross the Great Wall in 1644, when the gates at Shanhaiguan were opened by Wu Sangui, a Ming border general who disliked the activities of rulers of the Shun Dynasty. The Manchus quickly seized Beijing, and defeated the newly founded Shun Dynasty and remaining Ming resistance, to establish the Qing Dynasty.Under Qing rule, China's borders extended beyond the walls and Mongolia was annexed into the empire, so construction and repairs on the great wall of china were discontinuedz

Christ The Redeemer Statue

Christ the Redeemer is a statue of Jesus Christ in Rio de Janeiro, Brazil. The statue stands 38 metres (120 ft) tall. It weighs 635 tonnes (700 short tons), and is located at the peak of the 700 metres (2,300 ft) Corcovado mountain in the Tijuca Forest National Park overlooking the city. It is the tallest of its kind in the world. The statue of Cristo de la Concordia in Cochabamba, Bolivia is the second tallest, standing at 33 metres (110 ft) tall. It is made of reinforced concrete and soapstone.
A symbol of Christianity, the statue has become an icon of Rio and Brazil.
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.The second proposal for a large landmark statue on the mountain was made in 1921 by the Catholic Circle of Rio. 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. 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. The statue of Christ the Redeemer with open arms was chosen.

Machu Picchu

Machu Picchu is a pre-Columbian Inca site located 2,430 metres (8,000 ft) above sea level. 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. The river is a partially navigable headwater of the Amazon River. 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 1460 AD 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 said who to have been forgotten for centuries when the site was brought to worldwide attention in 1911 by Hiram Bingham, an American historian. Since then, Machu Picchu has become an important tourist attraction. It has recently come to light that the site may have been discovered and plundered several years previously, in 1867 by a German businessman, Augusto Berns. In fact, there is substantial evidence that a British missionary, Thomas Payne, and a German engineer, J. M. von Hassel, arrived earlier than Hiram, and maps found by historians show references to Machu Picchu as early as 1874.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.

Roman Colosseum

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). 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, 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.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 to the amphitheatre.The roman colosseum is also depicted on the Italian version of the five-cent euro coin

Petra Jordan

Petra jordan is an archaeological site in the Arabah, Ma'an Governorate, Jordan, lying on the slope of Mount Horin 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 jordanis also one of the new 7 wonders of the world of the world. The Nabateans constructed it as their capital city around 100 BCE. 
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. In 1985, petra jordan was designated a World Heritage Site
History
The History of petra jordan begins with the Kites and cairns of gazelle hunters going back into the aceramic neolithic.clarification needed Evidence suggests that settlements had begun in and around there in the Eighteenth Dynasty of Egypt. It is listed in Egyptian campaign accounts and the Amarna letters as Pel, Sela or Seir). Though the city was founded relatively late, a sanctuary existed there since very ancient times. Stations 19 through 26 of the stations list of Exodus are places associated with petra jordan. Thispetra jordan of the country was biblically assigned to the Horites, the predecessors of the Edomites. The habits of the original natives may have influenced the Nabataean custom of burying the dead and offering worship in half-excavated caves. Although Petra is usually identified with Sela which also means a rock, the Biblical references refer to it as "the cleft in the rock", referring to its entrance. 2 Kings xiv. 7 seems to be more specific. In the parallel passage, however, Sela is understood to mean simply "the rock"

On the authority of Josephus Eusebius and Jerome assert that Rekem was the native name and Rekem appears in the Dead Sea scrolls as a prominent Edom site most closely describing petra jordan. But in the Aramaic versions Rekem is the name of Kadesh, implying that Josephus may have confused the two places.citation needed Sometimes the Aramaic versions give the form Rekem-Geya which recalls the name of the village El-ji, southeast of petra jordan. The capital, however, would hardly be defined by the name of a neighboring village.citation needed The Semitic name of the city, if not Sela, remains unknown. The passage in Diodorus Siculus which describes the expeditions which Antigonus sent against the Nabataeans in 312 BC is understood to throw some light upon the history of Petra,citation needed] but the "petra" referred to as a natural fortress and place of refuge cannot be a proper name and the description implies that the town was not yet in existence.[citation needed]
The Rekem Inscription in 1976The only place in petra jordan where the name "Rekem" occurs was in the rock wall of the Wadi Musa opposite the entrance to the Siq. About twenty years ago the Jordanians built a bridge over the wadi and this inscription is now buried beneath tons of concrete.
More satisfactory evidence of the date of the earliest Nabataean settlement may be obtained from an examination of the tombs. Two types may be distinguished—the Nabataean and the Greco-Roman. The Nabataean type starts from the simple pylon-tomb with a door set in a tower crowned by a parapet ornament, in imitation of the front of a dwelling-house. Then, after passing through various stages, the full Nabataean type is reached, retaining all the native features and at the same time exhibiting characteristics which are partly Egyptian and partly Greek. Of this type there exist close parallels in the tomb-towers at el-I~ejr [?] in north Arabia, which bear long Nabataean inscriptions and supply a date for the corresponding monuments at Petra. Then comes a series of tombfronts which terminate in a semicircular arch, a feature derived from north Syria. Finally come the elaborate façades copied from the front of a Roman temple; however, all traces of native style have vanished. The exact dates of the stages in this development cannot be fixed. Strangely, few inscriptions of any length have been found at Petra, perhaps because they have perished with the stucco or cement which was used upon many of the buildings. The simple pylon-tombs which belong to the pre-Hellenic age serve as evidence for the earliest period. It is not known how far back in this stage the Nabataean settlement goes, but it does not go back farther than the 6th century BC.
A period follows in which the dominant civilization combines Greek, Egyptian and Syrian elements, clearly pointing to the age of the Ptolemies. Towards the close of the 2nd century BC, when the Ptolemaic and Seleucid kingdoms were equally depressed, the Nabataean kingdom came to the front. Under Aretas III Philhellene, the royal coins begin. The theatre was probably excavated at that time, and Petra must have assumed the aspect of a Hellenistic city. In the reign of Aretas IV Philopatris, the fine tombs of the el-I ejr type may be dated, and perhaps also the great High-place.

Taj Mahal India

The tajmahal india is a mausoleum located in Agra, India, built by Mughal Emperor Shah Jahan in memory of his favorite wife, Mumtaz Mahal.
The tajmahal india is considered the finest example of Mughal architecture, a style that combines elements from Persian, Ottoman, Indian, and Islamic architectural styles. In 1983, the tajmahal india 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 tajmahal india is actually an integrated complex of structures. Building began around 1632 and was completed around 1653, and employed thousands of artisans and craftsmen. The Persian architect, Ustad Ahmad Lahauri is generally considered to be the principal designer of the tajmahal india.
History
Soon after the Taj Mahal's completion, Shah Jahan was deposed by his son Aurangzeb and put under house arrest at nearby Agra Fort. Upon Shah Jahan's death, Aurangzeb buried him in the tajmahal india next to his wife.
By the late 19th century, parts of the Taj Mahal had fallen badly into disrepair. During the time of the Indian rebellion of 1857, the tajmahal india l was defaced by British soldiers and government officials, who chiseled out precious stones and lapis lazuli from its walls. At the end of 19th century British viceroy Lord Curzon ordered a massive restoration project, which was completed in 1908 He also commissioned the large lamp in the interior chamber, modeled after one in a Cairo mosque. During this time the garden was remodeled with British-looking lawns that are visible today.

In 1942, the government erected a scaffolding in anticipation of an air attack by German Luftwaffe and later by Japanese Air Force. During the India-Pakistan wars of 1965 and 1971, scaffoldings were again erected to mislead bomber pilots. Its recent threats have come from environmental pollution on the banks of Yamuna River including acid rain due to the Mathura oil refinery, which was opposed by Supreme Court of India directives. The pollution has been turning the tajmahal india l yellow. To help control the pollution, the Indian government has set up the Taj Trapezium Zone (TTZ), a 10,400 square kilometer (6462.26 square mile) area around the monument where strict emissions standards are in place. In 1983, the tajmahal india was designated a UNESCO World Heritage Site.
