Popular construction from the 17th-18th centuries formed by a circular stone and brick well (5 m diameter X 7 m high, approx.). A part of this well is underground (between two and three meters) and the other protrudes approx. 4 m, up to a vaulted ceiling (also made of stone and brick). The exterior walls are reinforced with buttresses and there are three barrel vault openings (windows or doors).
