Today, the castle consists primarily of two towers connected by a wall. In the outer walls, Roman columns were used as horizontal reinforcements, a feature often seen in fortifications built on or near former Roman sites. The rectangular west tower to the left of the entrance is the better preserved of the two. There is a large vaulted room scattered with old carved capitals and rusting cannonballs. A winding staircase leads up to the roof, where there is a small, domed Ottoman-era mosque.
