The castle of Anaktoroupolis in Nea Peramos
West of Nea Peramos, in the southern part of Eleftherai bay the ruins of a castle belonging to the Byzantine Anaktoroupolis are to be found. The castle was built on a hill above the sea offering control over the entire surrounding area to land and the bay. In the written sources that the city is preserved, it is mentioned from the 10th century AD, as Alectriopolis, later Alectoropolis and in the turbulent 14th c. as Anaktoroupolis and Eleftheropolis. According to the method of construction, and the inscription that survives in the southern precinct, two are the most important building phases:
In 1383 or 1387 it was occupied by the Ottomans. During the Ottoman rule the area must have been abandoned, whereas in World War I it was used as a camp for the Bulgarian army.
The precinct of the castle has a perimeter of 650m. occupying an area of 15.5 hectares and is preserved at a maximum height of 8.5 m. For greater reinforcement of the defense there were 13 towers, rectangular, circular and polygonal. In the southeast corner dominates the citadel with a height of 11.5 m. Below the sea surface there are parts of the port. The castle has recently undergone significant restoration work.
The access to the archeological site is made from the coastal national road Thessaloniki-Kavala through a dirt road from the intersection of Nea Peramos.
