The Prison Tower is erected in the lowest area of the town; the walls are mainly extended by the Montesta Street, next to the Parish Church. They do not have a certain origin, but similarities with the terraced church, dated from the 12th century, can be observed.
The square-based tower still has the access door and some windows. The interior hoses a staircase that communicates the upper floors. It is attached to the most ancient dwelling complex in the town and is relatively in good condition.
Access to the old part of the town.
