One very distinctive trait of the pre-Hispanic culture in Gran Canaria is the existence of troglodyte granaries, many of them collective and fortified or very hard to access, fundamentally intended for keeping and conserving excess farming products.
One of the most outstanding examples is the Álamo Granary, in the troglodyte complex of the Mesa de Acusa. The granary comprises two levels: a first level that is accessed through a passage in the rock, with marks suggesting it was closed with a door; and a second level that is accessed from the first and after a difficult climb up the plateau wall. This second level comprises a chamber around which 12 silos are arranged. The difficulty to reach this second level means that part of the original content of the silos has been preserved, providing unique information on economic strategies concerning food production in the aboriginal period.
