Strymonian Gulf

East of Chalcidice, the Strymonian Gulf receives the river from which it takes its name. Near the river mouth stood Eion, the port of ancient Amphipolis, which Athens used as a military and commercial base. After Amphipolis declined, its inhabitants likely moved to the port, rebuilt by the Byzantines as Chrysopolis. In 1367 two Byzantine officials built a fortified tower nearby to protect lands they had given to the monastery of Pantokrator on Mount Athos.
