In 1911 Hiram Bingham, a pre-historian with a love of exotic destinations, set out to Peru in search of the legendary city of Vilcabamba, capital city of the last Inca ruler, Manco Inca. With a combination of doggedness and good fortune he stumbled on the perfectly preserved ruins of Machu Picchu perched on a cloud-capped ledge 2000 feet above the torrent of the Urubamba River. The buildings were of white granite, exquisitely carved blocks each higher than a man. Bingham had not, as it turned out, found Vilcabamba, but he had nevertheless made an astonishing and memorable discovery, which he describes in his bestselling book LOST CITY OF THE INCAS.
