A portico in double order, the lower one Doric and the upper one Ionic, surrounded the Forum on three sides, except the northern side. The square was a pedestrian precinct with the service streets blocked through special rocks. The Forum was the political, economic, commercial, religious center of the city. On the southern side of the portico some monumental bases of imperial honorary statues are visible, while along the porticoes there are some statues of nobles citizens. Public, religious, economic buildings was sited around the Forum, almost hidden by the portico, while the only completely visible building was the Temple of Jove. In the north the Forum is closed by two triumphal brick arches, which at one time were faced with marble.
