In November 2012, excavations continued in the northern part of the forum. A quadrangular trench (8 × 3 m) was dug in the area north of the yellow tufa opus quadratum wall, in correspondence with the large opening that went out of function in the Roman period. The excavation aimed to 1) continue investigations in the forum’s northern sector; 2) recover the stratigraphic sequence in areas not yet investigated; 3) expose structures in areas not completely excavated during previous campaigns.

The removal of the surface layers of soil, compromised by modern agricultural activity, revealed layers of collapsed loose building rubble (fragments of tufa, brick, tile, cubilia), overlying a layer of crushed tufa, recognized in the test pits dug near the walls. Cleaning of this context revealed the foundation offset of the opus quadratum wall and the level of the threshold relating to the opening that was later blocked.

Traces were identified of the re-working of the corner pillar of yellow tufa blocks, situated west of the opening, probably undertaken at the same time as the interventions on the structures during the 1st century B.C. In the small area investigated, the floor level was not reached. The presence of large fragments of opus signinum attested its partial destruction. The discovery, along the wall, of numerous joining amphora fragments, kitchen ware and internal red-slip ware pottery, gives a preliminary date for the last phases of occupation and the abandonment of the excavated area of between the 3rd and 4th century A.D.
