Moray is an archaeological site in Peru approximately 50 kilometres northwest of Cusco on a 11,500 foot high plateau. The site contains unusual Inca ruins, mostly consisting of several terraced circular depressions, with depths as large as 98 feet.
The purpose of these depressions is uncertain, but their depth, design, and orientation with respect to wind and sun creates a temperature difference of as much as 27 °F between the top and the bottom. Because there is also an irrigation system, the site was thought to be used for farming different varieties of maize and other vegetables that required different climates. Though the technology is attributed to the Inca, the lower portions of the complex are thought to date from the pre-Inca Wari culture.
