Cenobio de Valerón Historical milestone · Santa María de Guía de Gran Canaria, Gran Canaria - Noroeste, Las Palmas Collective aboriginal granary cut into the Valerón gorge, with more than 350 artificial chambers spread across several levels of an almost vertical wall, used until the conquest to store grain under family ownership seals. The name 'cenobio' (monastery) reflects a mistaken 19th-century idea that confused it with a convent where young nobles were confined.
