The surviving agora is located in the northwest of the colonnaded street and practically merges with the theater stage. The entrance to it lies through the gate, which has the name propylion (columned monumental entrance), located opposite the museum. It is surrounded on all sides by granite columns, which have the “atik-ion” order in their pedestals, and the “Corinth” order on the tops. After the architrave, the sloping roof is wooden, and in the four corners of the agora there are pedestals with statues (exedras).
Behind the southwestern exedra, merging with the stage of the theater, there was a semicircular monumental structure - toilets (latrium), covered with a vault. This is the only well-preserved and very beautifully decorated ancient toilet in Anatolia. It has twenty-four seats, its walls were covered with marble, and on the floor - a mosaic. The sewerage for sewage was under the stone toilet seats, and in front of it was an open fresh water canal, which ensured cleanliness.
Agora at one time had two entrance gates, which were closed by walls. Agora in Side and all other structures in it were erected in the second century AD. It was built specifically near the theater, on the recommendation of Vitruvius, an ancient Roman architect, so that theater spectators could take cover during sudden precipitation.
In the center of the square, which has the shape of a square, you can see traces of a round temple of the goddess of fortune and the case of Tyche. She, according to legend, ruled the fate of the city. In honor of the goddess, a temple was erected with a place of worship; columns with cornices are located around it.
