The flour mill of Morisco-era origin in Fuentes de Ayódar, with its 15th-century mill pond, is one of the municipality's most distinctive heritage features. Its exact date of construction is unknown, although the Carta-Puebla (founding charter) of 1611 already refers to it, confirming its existence from at least that time.
