Cusco and the Sacred Valley

The Inca capital of Tawantinsuyu, conquered by Francisco Pizarro in 1533, sits at 3,400 metres and contains the most concentrated collection of Inca and Spanish colonial architecture in the Americas -- including the Coricancha temple complex, built with such precise stonework that a sheet of paper cannot be inserted between stones. The Sacred Valley of the Incas stretching from Cusco to Aguas Calientes contains Ollantaytambo, Pisac, and Moray (a set of concentric circular terraces used as an agricultural laboratory) within 80 kilometres.
