Guide of Eastern Macedonia & Thrace

In the third quarter of the 7th century BC, Parian colonists from Thasos founded Oisyme at the bay of Eleftheres, on the west end of Nea Peramos of the Prefecture of Kavala. The ancient settlement rests on a rocky fortified hill, on the top of which are the ruins of an ancient wall as well as the remains of a building, probably a sanctuary dedicated to Athena. A cemetery with graves of the 7th, 6th and early 5th centuries BC is also preserved. It was renamed Emathia during the reign of Philip II (356-336 BC), when it became a Macedonian colony.
The Byzantine Anaktoroupolis extended on a low hill to the northeast of Oisyme in the Byzantine times (324-1453 AD). During the 10th century, it is recorded in the sources as Alektryopolis and then, in the 11th-13th centuries as Alektropolis and finally, in the 13th-14th centuries as Eleftheropolis and Anaktoropolis. In the 9th century, Anaktoroupolis is a bishopric city under the administration of the Metropolis of Philippi. According to a plinth inscription, a fortress was constructed in the 12th century enclosing the city that persisted until the Ottoman occupation in the 14th-15th centuries.
Finds from the site are exhibited in the Kavala Archaeological Museum.
