The section separating the peninsula from the main land was erected in 2nd century BC during the Hellenistic period, among the walls of the ancient city of Side which have survived through the present day.
The walls on the side of the peninsula facing the sea were somehow demolished and than they were modified, constructed or repaired all over again during the Roman and Byzantine periods. Today, among those the walls on the southern edge have been buried under the sands.
On the neck section of peninsula the walls which imply that the city became smaller for a while, date back to 4th century AD.
The way in which the Hellenistic walls were constructed is very interesting. The inner side of these walls decorated cornice among the patterns of their outer surfaces and have three floors and each floor was built slightly towards the front as compared to the floor on which it seats, and as a result 2 paths were obtained on the walls for the soldiers. On the upper floor a simple balustrade wall is found while there are crenel holes on the walls in the central floor. In this way from both floors the possibility to fire attackers were provided.
The rooms used as depot etc at some points and the lower floors of the walls include only a bearing wall at some other points. At several points in these defense system strengthened with towers ( the total number of the towers are 13, some having a semi-circular and some others having a rectangular plan ), it is interesting that the paths of walkers which extended al along the walls ceased at the points corresponding to the rear section of the towers. It is possible that in these sections there were wooden bridges to provide for the passage.
