The site preserves a long portion – 2.40 meters wide and 4 meters high – of the ancient city walls, consisting of two outer faces in sandstone blocks filled filled with stone and lime. At its base is a moat for collection of the runoff from the hillside. Between the middle of the 1st and 2nd century A.D. the walls lost their defensive function and were reused as terracing structures and containing walls, as can be seen from the remains of a basin paved in terracotta, possibly used for processing oil, which was overlaid on the walls.
