About Machu Picchu
Known as the Lost City of the Incas. Built as an estate for Emperor Pachacuti. Rediscovered by Hiram Bingham in 1911, though locals always knew of it. Over 150 buildings including temples, sanctuaries, and houses. Stones fit together so precisely that no mortar was needed. The Intihuatana stone marks the equinoxes precisely.
