Machu Picchu was built around 1450, at the height of the Inca Empire and was abandoned in 1572. It was thought to be an estate of the Inca emperor Pachacuti, who ruled 1438 to 1472.
This citadel is probably the most familiar icon of Inca civilization.
Here is one in a series of fountains that supplied Machu Picchu’s inhabitants with clean, fresh water. Inca engineers brought water in carefully designed channels from a pair of rain-fed springs almost half a mile away from the first fountain.
