There are 100 years since it was discovered the Incan citadel Machu Picchu (“the old peak” in the Quechua language). Hiram Bingham, the one who discovered the citadel in 1911, gave it the name of the mountain on which it is sited, and the original name was never discovered.
Machu Picchu is located on a mountain ridge, 450 meters above the Urubamba River, a tributary of the Amazon. The entire complex covers 32.500 hectares, but the built area, which includes 172 dwellings, is focused on a plateau measuring 530 meters in length and 200 meters in width, being surrounded by terraces devoted to agriculture. It is believed that almost 1,000 people lived in the ancient Incan city built in the fifteenth century.
