Watchtower and modern defense, with a circular floor of 6.5 m in outer diameter and about 10 m high, from the base to the crown. The work is made of masonry, with walls 0.80 m thick, kept the same on all floors. The access to the tower (115 cm wide and 180 cm high), located on the ground floor, faces east and has a stone lintel and chopped stone jambs. In addition, several loopholes and three square windows are also observed at the top. The structure is topped by a set of three gargoyles for drainage and, at the top, three corbels, which must have supported three battlements, currently being rebuilt. Inside the tower, a basement has been preserved covered with a stone vault tied with lime mortar, which is accessed through a small rectangular opening of about 60 x 70 cm. located on the outside floor, and which had the function of a cistern. There is nothing left of the three ceilings that were there: those on the ground floor and the two upper floors. On the wall of this basement there is a written inscription from 1615. The technique used in construction is ordinary masonry, plastered on the outside, with a very uniform appearance throughout the volume.
