The flat area located just to the west of the theater was apparently used as an agora at Tlos. The agora was the focus of commercial, political and administrative lives, and the center of social and cultural activities in cities. The two-storey shops bordering the stadium area from the east have clear links with the agora. A recently built modern road cut off the link between these shops and the agora. This two storey shops apparently served as a transition between the agora and the stadium in this sloppy area. This is to say that the second floors of the shops were open to the agora, while the first floors to the stadium area. Because it is not excavated yet, it is difficult to determine the architectural features of the agora. It is now partially covered by soil accumulated through erosion. In addition, it is clear that the re-use of this area in the Early Byzantine period resulted in large scale alterations to a great extent. Most of the architectural blocks detected over the surface of the agora date to the second century A.D. in the Roman period. However, the planning of the monumental structures such as the bouleuterion, the stadium, and the theater in the Hellenistic period imply that the agora was also in existence in this period. A third century B.C. statue base related both to the theater and the agora supports this date.
