Machu Picchu was built around 1450, at the height of the Inca Empire. Its construction appears to date to the period of the two great Inca rulers, Pachacutec Inca Yupanqui (1438â71) and TÃºpac Inca Yupanqui (1472â93). It was abandoned just over 100 years later, in 1572, as a belated result of the Spanish Conquest.
