Perched on a ridge 2,430 meters above the Sacred Valley, Machu Picchu is the crown jewel of the Inca Empire — a 15th-century citadel of terraces, temples and mist that vanished from the world until 1911.
Built around 1450 under the emperor Pachacuti and abandoned a century later, it was brought to global attention by explorer Hiram Bingham in 1911.
