In the centre was the Agora of Hippodamus; on the western margin of the Cantharus harbour extended the emporium, or Digma, the centre of commercial activity, flanked by a series of porticoes; at its northern end, near the entrance to the inner harbour, was another Agora, on the site of the modern market-place, and near it the µa?cp l OTOa, the corn depot of the state.
The agora is of unsymmetrical form; its sides are bordered by porticoes, interrupted by streets, like the primitive agora of Elis as described by Pausanias, and unlike the regular agoras of Ionic type.
Most of these porticoes were of Roman period - the finest of them were erected, as we learn from inscriptions, by a lady named Epigone: one, which faced south, had a double colonnade, and was called the Bai-rn: close to it was a large exedra.
It joined with Naples to erect one of the finest porticoes of Constantinople at the time of its construction.
Recent excavations have revealed porticoes, a gateway and other buildings, and also the remains of several colossal early statues, the best preserved of which is now in the museum at Athens.
