Machu Picchu remained hidden during centuries until 1911, date on which professor Hiram Bingham made known it in the whole world.
Machu Picchu is not only one jewel of architecture INCA, the crowned city is especially the supreme expression of the work of the man in harmony with the environment; it is a citadel located at the top of a narrow peak above the turbulent river, beaten by the intense wind of the escarpées mountains of the Amazonian buttress
The archaeological unit is divided into two sectors called Agricole and Urbain where are places, temples, palates, warehouses, workshops, staircases and fountains which are arranged on the two sectors out of some 10 to 20 ha each one.

It is obvious that Cusco, the capital of the State INCA, was taken for model in the architectonic distribution of the site bus Machupicchu has all the urban elements adapted to the sinuosity of the ground and the various unevennesses.
The archaeological excavations carried out after the visit of Bingham made it possible to conclude that the ground was embanked as a preliminary with a material which does not belong to the site, since the ground of this last, formed by a granite base, is very low in fertile ground.
