The Forum of Lucentum was distributed in two separate areas with a street passing through the middle, access to which could be closed as specific times with two gates of double-doors, which would permit the passage of carriages

In the northeast corner sat the temple, elevated on a platform or podium, with a small annex (Erario) which contained the city’s Treasury. The temple would serve as a place of reunion (Curia) for the city Assembly or Senate (ordo decurionum).
