the geophysical survey company Eastern Atlas with the objective of locating and mapping more remains of subsurface archaeological features in Trea. Also the recent study of the Roman pottery to deliver chronological clues and help to determine functional zones as well as the study of stone architectural decoration to gain more insights in the embellishment of the town, has led to more information. 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. The forum was probably located near the intersection of the north-south axis with the main decumanus. Although a major part of the ancient town is built over by the houses and streets of Villa Potenza, several large buildings can be distinguished in the crops of the fields north of the central area. One of them is a rectangular building (at least 18 x 33 m) oriented northwest-southeast, perpendicular to the main decumanus and possibly bordering a forum on its south. This was probably the main temple (Capitolium?) of Helvia Ricina. Other traces of buildings may be seen in the fields: several large domus, a large cistern, which may point to a nearby public facility or baths and a row of similar rectangular rooms, flanked by a corridor or portico suggest a set of tabernae or possibly a horreum. The latter is supported by the presence of many dolia and amphora sherds found at this location. There are also signs of habitation outside the walls, more specifically directly southwest of the town, outside the presumed location of the southwest gate and alongside the road to Trea as well as at the northeast side of the town were crop-marks and a wide scatter of Roman material point to an extramural settlement. The theatre is the only well-preserved remain of the city above ground. It has a cavea of 71.80 m diameter and is now surrounded by modern houses of Villa Potenza. During an aerial
