The area traditionally referred to as ‘acropolis’ is a broad plateau, slightly elevated above the rest of the town and stretching out in the Adriatic Sea between two natural inlets. Within this area, different phases of Egnazia’s millennial history overlap, starting with the fortified Bronze Age village until the site’s abandonment in the Middle Ages. The traces of the protohistoric settlement are followed, starting from the 6th century B.C., by the structures of several buildings of worship characterizing the religious function of this area until the age of Trajan, when a big sanctuary is built in the middle of the plateau. After being transformed during the Late Roman period, the acropolis is fortified by the Byzantines and, after the 6th century A.D., embraces the settlement within a new surrounding wall, where also the medieval village, developing without an orderly plan, will be active until the 13th century.
