It seems that the layout of the town was a fairly regular and quite flat, almost rectangular area of c. 22 ha. The valley road from Trea to Potentia crossed roughly the centre of town from southwest to northeast and served as its main decumanus. One main NW-SE axis, if confirmed by further fieldwork, could have linked the main decumanus with the Roman bridge over the Potenza, which earlier observations located a few meters upstream from the present-day bridge. This street passed directly in front of and parallel with the stage building of the theatre.
