National Geographic : 1916 May
Photograph by Hiram Bingham A BIRD'S-EYE VIEW OE OLLANTAYTAMBO Here the Peruvian Expedition of 1915 made its headquarters, in a rejuvenated Spanish building, seen inthecenter foreground attheright of the long church. The ruins in and about Ollantaytambo are among the most interesting in South America, and consist notonly offairly recent Inca structures, less than 400 years old, but of megalithic remains of unknown antiquity. The end ofthe promontory was strongly fortified and almost impregnable. The banks of the Urubamba River in the distance are terraced. The Urubamba Valley atthis point isstill intensely culti vated on remarkable great terraces that were laid out by the Incas and their predecessors many centuries ago (see "Staircase Farms oftheAn cients," by O. F. Cook, in this number).
