Moray Ruins

Moray is an archaeological site in Peru approximately 50 kilometres northwest of Cuzco on a high plateau at about 3,500 metres and just west of the village of Maras. The site contains Inca ruins, mostly consisting of several terraced circular depressions, the largest of which is approximately 30 m deep. As with many other Inca sites, it also has an irrigation system.

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 5 °C between the top and the bottom.
