The 2015 campaign concentrated on the area in front of the Casale Alibrandi in the locality of Bufalareccia (Zone D), where during the 18th and 19th centuries, the remains of the ancient city were excavated.
Three sondages were opened in an area situated immediately east of the SS 1 (via Aurelia). The first (_sondages_ 1), revealed a stretch of the 3rd century B.C. castrum walls, built in opus quadratum of blocchi scaglia, about three metres wide. A number of rectangular rooms, aligned east-west, were present directly north. At present, their function is unknown. These rooms, datable to the Republican period, had already been identified by a magnetometer survey undertaken in 2011, which made it possible to reconstruct the topography of the ancient settlement.
Several areas of a probable “piazzale” paved in basolato, in the area immediately outside the castrum (to the south) appeared in sondages 3. A number of structures faced on to these areas, most had been obliterated by a modern road. Some, like the basolato, were documented during a rescue excavation in the 1980s.

Further north (_sondages_ 2), the excavation uncovered a series of structures relating to three occupation phases, whose chronology remains to be clarified.
The latest was attested by four walls in opus mixtum one metre wide, in a radial arrangement and orientated east-west.
The particular form of this structure suggests it was a substructure for a semicircular building, possibly a cavea.
The project to enhance all of the area investigated from 2010 onwards (zones A and D) was begun having been recently approved by the local administration. The project will provide for the restoration of the ruins uncovered to date, with a view to the creation of an archaeological park in the future.
