Of the fortification, 80m of the eastern wall survive, which includes 2 towers and 230m of the southern wall, which includes 6 towers and several of the staircases. In addition, the southeastern gate, which is preserved intact and is 2.10m wide, reached our days. It is located in a recess and the lintel was built with stone blocks 3m long.
There is an inscription on the exterior wall, to the north of the surviving gate.
The inscription says: ΔΑΜΟΣΙΟΝ ΤΟ ΧΩΡΙΟΝ ΠΕΝΤΕ ΠΟΔΕΣ ΑΠΟ ΤΟ ΤΕΙΧΕΟΣ which could be translated as: PUBLIC ACCESS FROM 5 FEET OF THE WALL.
And it established the width of the restricted area outside the wall that had to remain free for defensive uses.
This was so that if the city were under attack, the attackers would not jump to the wall from the roofs of the neighboring houses built outside…
This inscription is believed to be from 325-300 BC.
