[Q]: Most archaeologists believe that Machu Picchu was constructed as an estate for the Inca emperor Pachacuti (1438 -- 1472). Often mistakenly referred to as the 'Lost City of the Incas' (a title more accurately applied to Vilcabamba), it is the most familiar icon of Inca civilization. The Incas built the estate around 1450 but abandoned it a century later at the time of the Spanish Conquest.
