It was possibly an Inca agricultural research centre where crop experiments were carried out at different heights, the layout of its platforms produces a gradient of microclimates having the centre of the concentric circular platforms a higher temperature and gradually reducing outward to temperatures lower.

These salt mines are also known as "salt mines". They are formed by about 3000 small wells with an approximate area of about 5 m². In times of drought these are filled with salt water that comes from a natural spring that is located above the wells, when the water evaporates the salt crystallizes. When the salt reaches about 10 cm high from the floor it will be removed and then packed in cloth sacks and sent to the markets of the region; today that salt is being iodized by state standards
