From ancient Eion to Byzantine Chrysopolis
The fortified enclosure near the mouth of the river Strymon is identified with the ancient city of Eion and the Byzantine Chrysopolis. From the various references in written sources it is certain that Chrysopolis developed from the 10th century and played a role in the maritime transport of products produced in the surrounding fertile areas.
In the 14th century it passed from Byzantine hands to the Serbs, then again to the Byzantines, before finally being occupied by the Ottomans. By the mid-16th century Chrysopolis was an important city of commercial and strategic importance. After two centuries of decline, Chrysopolis experienced new growth at the beginning of the 19th century.
On your visit to the site you will see the enclosure, which is preserved in fragments, elsewhere at a satisfactory height and elsewhere not at all. To strengthen the castle there were towers around the perimeter.
