The full purpose behind these concentric terraces isn’t fully known. However, it is widely believed that the ruins were once an agricultural laboratory used by the Incas. The circular terraces that lie here are thought to have been used as an agricultural research station. Their depth, design, and their orientation with regard to the sun and wind are all telltale signs that they have a specific purpose. Because of the different conditions at each level of the terraces there is a difference in temperature of 15 °C (27°F) from the top to the bottom.
