Machu Picchu (of the southern Quechuan machu pikchu, " Old Mountain ") is the contemporary name that is given to a llaqta (former Andean settlement Inca) of stone constructed principally in the middle of the 15th century in the rocky promontory that joins the mountains Machu Picchu and Huayna Picchu in the oriental slope of the Central Andes, to the south of Peru. His original name would have been Picchu or Picho.
According to documents of middle of the 16th century, Machu Picchu it would have been one of the residences of Pachacútec's rest (the first emperor Inca, 1438-1470). Nevertheless, some of his better constructions and the evident ceremonial character of the principal exit ramp to the llaqta would demonstrate that this one was used as sanctuary religioso. Both uses, that of palace and that of sanctuary, would not have been incompatible. Some experts seem to have rejected, on the other hand, a supposed military character, by what the popular epithets of "strength" or "citadel" might have be overcome.
Machu Picchu is considered to be at the same time a masterpiece of the architecture and the engineering. His peculiar architectural and landscape characteristics, and the veil of mystery that has woven around it good part of the literature published on the site, have turned it into one of the most popular tourist destinations of the planet.
Machu Picchu is in the List of the Heritage of the humanity of the UNESCO from 1983, as part of the whole cultural set and ecological acquaintance under the name Machu Picchu's historical Sanctuary.
On July 7, 2007 Machu Picchu was declared as one of the new marvels of the world in a ceremony realized in Lisbon, Portugal, after the participation of hundred million voters of the entire world.
