Note there is the agora, a large open space, and the agora building, a solid set of shops and storage space. It is rather ruined, it is hard to work out what one sees. The agora as open space was to the east of the area with shops and storage. It now is filled with lots of fragments that seem to be waiting reconstruction.
To the west of the shops, at the edge of the stadium, is a row of columns that may have been part of the shopping area, but I did not find it described.
