These limestone pillars are an outcrop lower down the mountain from the village of Comares. The village itself is built on top of a much larger mass of the same pillars, which are interspersed with pink granite. This natural fortification was the reason for the settlement being built in such an unusual situation. At the base of the pillars on which Comares is built are a series of natural springs. The most prolific of these was connected to the village by a fortified walkway, parts of which were cut in to the cliff. Water was also transported up by donkey and stored in cisterns which still exist in the cemetery at the eastern end of the village. This plentiful water supply ensured the settlement's continued existence.
