Salinas de Maras in Cusco, or maras salt mines as they are also called, are salt mines whose exploitation is as old as the Tahuantinsuyo. Located on the slope of the hill, the salt pans in the form of terraces or platforms is crossed by a stream that nourishes the pools with salt water. The use of the Salt of Maras dates from thousands of years and is inherited in each family, but it is managed in a communal way. The name of the salina in Quechua is kachi Raqay and is composed of about five thousand pools of about 5 square meters each, the water seeps into the pools and evaporates by the action of the intense sun, causing coarse salt crystals to sprout , After 1 month the salt reaches 10 cm. of height and has to be harvested.
