Opening hours:
The exterior may be visited; the interior only on occasion.
The tower looks like a four-level truncated pyramid, with solid
walls and a 10th-century barrel vault. Part of the walls that
once surrounded the village has been preserved. A further level,
with balconies, was added in the 11th century. Elevated access
with horseshoe arch. The tower is known as the Torre de Doña
Urraca, since doña Urraca was buried there in 1005.
