Seven Wonder of the World- Machu Picchu-Peru

Machu Picchu is 80 kilometers northwest of Cusco, on the crest of the mountain Machu Picchu, located about 2,350 meters (7,710 feet) above sea level. It is one of the most important archaeological sites in South America and the most visited tourist attraction in Peru.






The central buildings of Machu Picchu use the classical Inca architectural style of polished dry-stone walls of regular shape. The Incas were masters of this technique, called ashlar, in which blocks of stone are cut to fit together tightly without mortar. The Incas were among the best stone masons the world has seen, and many junctions in the central city are so perfect that it is said not even a blade of grass fits between the stones.





The Intihuatana stone is one of many ritual stones in South America. The Spanish did not find Machu Picchu so the Intihuatana Stone was not destroyed as many other ritual stones in Peru were. These stones are arranged to point directly at the sun during the winter solstice. Intihuatana also is called "The Hitching Point of the Sun" because it was believed to hold the sun in its place along its annual path in the sky. At midday on March 21 and September 21, the equinoxes, the sun stands almost above the pillar—casting no shadow at all.Researchers believe that it was built as an astronomic clock or calendar.





Machu Picchu was constructed around 1462, at the height of the Inca Empire. It was abandoned less than 100 years later. It is likely that most of its inhabitants were wiped out by smallpox before the Spanish conquistadores arrived in the area, and there is no record of their having known of the remote city. Hiram Bingham, the credited discoverer of the site, along with several others, originally hypothesized that the citadel was the traditional birthplace of the Inca of the "Virgins of the Suns".










Another theory maintains that Machu Picchu was an Inca "llacta", a settlement built to control the economy of these conquered regions. Yet another asserts that it may have been built as a prison for a select few who had committed heinous crimes against Inca society.
