What happened
High in the Urubamba Valley north of Cuzco, Pachacuti founded the settlement now known as Machu Picchu, 'old hill,' around 1450 as his personal imperial estate. World History Encyclopedia describes competing theories about its purpose, fortress, retreat, symbol of Inca power, ceremonial site, but notes the architecture is dominated by religious structures, including the Intihuatana carved stone used for solar observations and a chamber carved from bedrock as a shrine to Inti. The site held perhaps 1,000 residents at its peak and was linked to nearby valley settlements by a dedicated road. On Pachacuti's death ownership passed to his descendants. The Inca abandoned the site before the Spanish conquest, and Pizarro's forces never found it. UNESCO's World Heritage listing calls it probably the most amazing urban creation of the empire at its height, its walls and terraces built to look like extensions of the mountain's own rock.
Why it matters
Machu Picchu's survival, unlooted and unknown to the Spanish, preserved an intact example of Inca stonework and religious architecture that the conquest destroyed almost everywhere else, including at the Coricancha in Cuzco itself. Its function as a personal royal estate, rather than a fortress or a last capital, corrects the popular myth of a hidden refuge city.
How we know
The purpose of the site is still debated among scholars, since no Inca text explains it directly; the religious-site interpretation rests on the layout of the buildings and the astronomical alignment of features like the Intihuatana stone, as documented by World History Encyclopedia and UNESCO's official heritage listing.
