The castle of Kavala dominates the tip of the peninsula where the old town is located. Over the centuries it has undergone successive reconstructions and modifications by the Byzantines, Venetians and Ottomans. Its present structure was built in the first quarter of the 15th century on foundations from the Byzantine period. Today, the castle (acropolis) is a prominent historical site and hosts cultural events in its open-air theatre, offering visitors a glimpse of the region's rich history and breathtaking views of the city and the Aegean Sea.
