Plan:
Abuts peribolos wall of Sanctuary of Poseidon on southern end running north then west to the western coast of the peninsula. Ten towers of varying size at irregular intervals. A small gate between (counting from the wall's southern end) towers 2 and 3, was enclosed by a later bastion. The main entrance was at the western end.
History:
The promontory was fortified during the Peloponnesian war. The small gate near the sanctuary later became an interior entrance to the bastion, which may date to 263-229 B.C. The section of the wall running east-west was less finely built than walls running north-south, possibly because steeper terrain there offers greater natural protection. The main entrance toward the western end was protected by a large rectangular building, possibly a guard house or barracks.
