Valerón's "monastery" is an archaeological site on the Spanish island of Grand Canary, in the municipality of Santa Maria de Guia, on Valerón's cliff. It is the largest pre-Hispanic collective granary built before Roman times and used by the island's inhabitants until the conquest of the island at the end of the 15th century.
Close to Gáldar Painted cave, it is one of the emblematic sites of Grand Canary and is listed as a Spanish Property of cultural interest.
