Cusco, is located in the South - Eastern region of Peru. As the “Archaeological Capital of America”, Cusco was a sacred city and capital of the empire of the Tahuantinsuyo, and it was extended by four regions which included great parts of Ecuador, Colombia, Peru, Bolivia, Argentina and Chile. The city of Cusco was the Andean State Capital of Inka's empire. Cusco is actually, with its impressive cultural heritage, the main attraction in Peru and the most visited. The contrast of the blue sky with the wonderful landscape makes it an unforgettable city. Nowadays, when you walk around the city and you can see the streets with colonial and spanish houses which are built with Incan stones, you will realize how important the city was in the ancient times.
Machu Picchu or Machu Pikchu (Quechua machu old, old person, pikchu peak; mountain or prominence with a broad base which ends in sharp peaks, "old peak", pronunciation [ˈmɑtʃu ˈpixtʃu]) is a 15th-century Inca site located 2,430 metres (7,970 ft) above sea level. It is located in the Cusco Region, Urubamba Province, Machupicchu District in Peru. It is situated on a mountain ridge above the Sacred Valley which is 80 kilometres (50 mi) northwest of Cusco and through which the Urubamba River flows. Most archaeologists believe that Machu Picchu was built as an estate for the Inca emperor Pachacuti (1438–1472). Often mistakenly referred to as the "Lost City of the Incas", it is the most familiar icon of Inca civilization.
The Incas built the estate around 1450, but abandoned it a century later at the time of the Spanish Conquest. Although known locally, it was unknown to the outside world before being brought to international attention in 1911 by the American historian Hiram Bingham. Since then, Machu Picchu has become an important tourist attraction. Most of the outlying buildings have been reconstructed in order to give tourists a better idea of what the structures originally looked like. By 1976, thirty percent of Machu Picchu had been restored. The restoration work continues to this day. (Source: Wikipedia)
