The qollqas Colcas or warehouses or barns were located in stages over the hillsides, into these large deposits the remainings of seveal products were stored, products such as grains, corn, quinoa, dried potatoes or potato flour, salted meat or chalona , etc .
The construction was very elaborate, since Colcas should have both, a good ventilation and drainage system. Each village had its own Inca Colcas strategically located in areas where there was more air intake so that you can keep food fresh.
The colcas were of two types: Circular and rectangular shaped, the circular ones were of 2-6 meters high with one door towards the mountains , and the rectangular ones , from 3 to 10 meters high , usually two doors , some were divided in two rooms.
The size of the gates were small , unlike the gates of other structures , they were always constructed in groups , never isolated from each other , the groups could be at least 4 up to 497 stores.
Its shape and utility were closely related to function. Corn always was stored in circular colcas while the tubers were stored in rectangular Colcas .
