The fort walls preserve five stone carvings from older construction periods. The southwest bastion has a carving of a wild creature with its tail between its legs, facing a man who raises his arms. Two abstract patterns (helix and circle with unknown content), a hunter shooting a beast, and an animal chained to a cypress adorn the northeast bastion. The latter is a common decorative pattern found in many defensive projects dated to the period of Ali Pasha. There is no agreement on the dating of the carvings or whether they are Venetian or Ottoman. Additional carvings have been lost.
