Machu Picchu
Machu Picchu, an ancient Inca fortress city in Peru. It is high in the mountains, about 50 miles (80 km) northwest of Cuzco. The ruins, discovered by an American, Hiram Bingham, in 1911, are remarkable for their imposing stone structures. Machu Picchu is thought to have been the final Inca refuge after the Spaniards came, 1533-34. [picture].)
