The ruins of a 4th century rectangular fortification tower have been identified in the area to the south of the modern village of Oenoe. It has been estimated that the building had four storeys and must have been over 16 m in height. The tower of Oenoe, erected in an uninhabited area, must have been part of a network of towerlike beacons. It was connected to the Eleutheres fort, as well as a nearby fortress situated to the northeast of the modern village. The latter, located at a site known as “Myoupolis”, is identified by some researchers with the ruins of the ancient settlement of Oenoe.
