The Department of Archaeology at Bologna University undertook its annual excavation campaign at Suasa between June and October 2011.

Work concentrated on the area of the main road running through the centre of the town, between the Domus of the Coiedeii and the House of the first style on the east side, and the forum to the west.

The road, exposed for about 80 m (4 m wide), was paved in basalt, had lateral sidewalks and the remains of lead fistulae were also present. From north to south the eastern frontage on the road comprised Building 7, the paving in front covered with small hexagonal terracotta tiles; the front of the Domus of the Coiedeii with at its centre Building S, Building 3 above the ancient entrance to the House of the first style, Buildings 5 and 6. In correspondence with the forum entrance the road’s basalt paving covered its foundations. As the forum was built during the Julio-Claudian period, the basalt paving can be said to be later. At the north-eastern corner of the forum the basalt road met a via glareata at a right angle. At this point, the underground drain collecting gutter water from the forum, also known from the old excavations, continued underneath the basalt paving towards the eastern edge of the excavation.

Below the basalt road (perhaps dating to the 2nd-3rd century A.D.), lay an earlier gravel road (first decades of the 1st century A.D.). The basalt road itself was overlain by a beaten earth road and compact rubble dating to the late antique period (perhaps the 4th century A.D.). The entire area was covered by agricultural soil (5th century A.D.).

The eastern street frontage was cut by an aqueduct dating to the end of the 19th century. To the north of the Domus of the Coiedeii was Building 7, accessible directly from the street. Mosty of this structure still lies beyond the excavation edge. Further towards the south, was the entrance structure to the Domus of the Coiedeii, only now completely visible.

The area between the Domus of the Coiedeii (2nd century A.D.) and Building 3, overlying the entrance to the House of the first style (2nd century B.C.), was occupied by a portico, circa six metres in depth. This formed a continuous series of covered areas, situated in correspondence with the structures behind. Some of these structures were distinguished by their more monumental aspect and the related sections of the portico floor were paved in stone (aula S, Building 6, unexcavated). Between Building 3 and Building 6 there was a similar structure without paving at the front (Building 5).

Therefore, to the south of the Domus, on the eastern frontage, there was a sequence of three buildings (3, 5, 6) with a portico in the front of them. The aule to the rear of the portico were raised on podia and entered via stone steps (on the line of the entrance to the Domus ).

The paving in the aula of building 3 dated to the 3rd century A.D. However, it seems that the original layout dated to the 1st century A.D., when the forum in front of it was built, and the underlying entrance to the House of the first style was demolished. In fact, building 3 stands exactly in front of the forum entrance and, therefore, must belong to the same building programme.
