The Fuente Grande, of medieval origin and listed as a Protected Historical Heritage Site, is a square structure with an octagonal bulbous roof. Its interior conserves masonry walls and a hemispherical dome supported by pendentives.
The water, of underground origin, is used for irrigation and, although its flow is low, it is never exhausted. At present, a drainage system maintains a constant flow into a basin, replacing an old piping system that is no longer functioning.
