Author 'Amivideo85' (Id 238101 ) : Machu Picchu is an ancient inca city in the Xv century Peru, perched on a rocky promontory that joins the mountains Machu Picchu (du quechua machu : vieille, pikchu : montagne), set of Huayna Picchu (young mountain) in the central Andes.
Machu Picchu, the sacred city forgotten for centuries, was discovered by the american archaeologist Hiram Bingham.
Machu Picchu would be one of the residences of the emperor Pachacútec or a religious shrine. The two uses are not mutually exclusive necessarily.
