Cenobio de Valeron is located in Isla de Gran Canaria, Spain
"High above a canyon, the Cenobio de Valeron is an impressive network of somewhere between 200 and 300 caves spread out over eight floors that were used as granaries. Connected by passages and steps and once flanked by high, looming towers, according to old accounts that have been preserved from the time of the Spanish conquest, the Cenobio de Valeron are spotted with round and rectangular chambers that were once dug by hand with animal bones and rocks as instruments"
