Late Roman Fortification Walls and Bouleuterion (Kadıoğlu, 2021, 173, Figure 63)
The ancient city of Teos was surrounded by several defensive walls built from the Archaic Period to the Roman Imperial Period. Archaeological, epigraphic, and historical sources provide information on the defence system of the Archaic, Classical and Hellenistic periods. During the Imperial period, Teos lived in peace for two and a half centuries as a city of the Province of Asia; in the Late Roman period, it was surrounded by a new wall, probably because of several barbarian raids. Enclosing an area of approximately 3 hectares, including the agora and the bouleuterion, the fourth city wall is reminiscent of a citadel and was built entirely from material reused from earlier structures.
This Late Roman Wall bordered the cavea of the bouleuterion to the south, west, and north and formed a tower (14.1) in the southwest corner of the cavea, was identified for the first time in 2013. Today, the bouleuterion, the small temple (Temple of Rome and Augustus) in the agora and the three structures formed by the agora are surrounded by the tall ruins of this defensive wall which is densely covered with vegetation. It appears as if the intention of the Romans was to create a citadel with this Late Roman defensive wall, which was only identified in the Greek and Roman city centre.
