Machu Picchu also called lost city of the incas, is a city in pre-Columbian well maintained, located at the top of a mountain, 2400 meters of altitude, in the valley of the urubamba river. It was built in the xv century under the orders of pachacuti. The place is probably the most typical symbol of the Inca Empire, both due to its original location and geological features, either due to its belated discovery in 1911. Only about 30 % of the city is of original construction, the rest It was rebuilt. The areas rebuilt are easily recognised by the fit between the stones. The Original building is formed by rocks bigger, and with sockets with little space between the rocks. Consists of two major areas: Agriculture formed primarily by terraces and enclosures of food storage; and urban, which stresses the sacred area with temples, squares and mausoleums real. The layout of the buildings, the excellence of the work and the large number of terraces for agriculture are impressive, highlighting the great capacity of that society. In the middle of the mountains, the temples, houses and graveyards are distributed in an orderly fashion, opening streets and enjoying the space with the stairs. According to the inca history, everything planned out for the passage of the sun God.
