We're at or near the Agora and Stoa. The area limited by the sacred precinct of Apollo to the north, by the street running in front of Fountain Building to the southeast and by the wall behind the monument dedicated to Vedius Capito to the west is termed the Harbour Agora. This was at the latest established in the Hellenistic Period. Only a quarter of it has been excavated so far. Excavations showed that, in addition to the official buildings such as the Monumental Fountain and the Stoa the Agora was embellished over the course of centuries with many monuments, statues and groups of statues standing on exedras of various forms.
To the north of the agora a single-naved building of 96,82 x 8,2 m had no shops and thus was clearly a promenade Stoa, it was built in the 3rd century BC. 44 Columns supported the front. A door cut into the middle part of the back wall in the 1st century BC provided to a large room of 12,81 x 9,05 m. In front of its back wall stood a high podium. A round altar found in fragments on the floor must have been placed on this podium. One of the central relief figures on the body of this altar is depicted carrying a winged baby and is clearly Aphrodite Euploia.

I am unable to precisely identify elements further.
