The area of the castle still visible is a four-sided plateau-shaped, closed to the east by the only ruins of the tower completely covered with climbing plants.
The area to the north and west is enclosed by a low retaining wall. Adjacent to the northeast corner of this first area, there is a second squared plateau enclosed to the northwest by a low retaining wall. The sides on the southeast are very steep.
The plateau, just described, occupies the highest part. It's therefore legitimate to consider that the ruins are the remains of the watchtower.
The castle dates back to the tenth century. The ruins, described, are near the parish church. They can be reached from the west by the last houses of the village, past the churchyard of the parish church and is bordered to the south by the church. To the east and north it is surrounded by wasteland.
