The acropolis is about 200 m long with interior walls and two exterior walls supported by towers. The exterior walls are built to the south, where the slope is slight. To the south and north of the acropolis, the main entrance of which is on the west side, there are small entrances, some of which have formed over time. In the center of the acropolis there is an executive building planned by Megaron and a large, well-preserved tower to the east which can control the peninsula in four directions.
