The fortress of Kephaloidion, built between the 5th and 4th centuries B.C., stretched out at the foot of the grand natural fortification and thus occupied a privileged position. Recent archaeological excavations, both in the necropolis and in the urban part, have shed light on the ancient site, documenting uses, customs, rituals, construction methods and bringing to light numerous finds, especially ceramics, which are evidence of a settlement that already had contacts with the Hellenistic centres present in Sicily.
