The archaeological campaign in 2015 involved an unexplored area with a total extension of 112 sq m, bordering to SW with the Settore Nord 2014 (the western part) and to SE with the area of the Domus del Labirinto investigated between 2001 and 2006 (the eastern part).

In the western part we have continued the investigation of the concrete floor, to whose renovation the fragment of polychrome mosaic discovered in 2014 and dated back to the middle Imperial age (end of the 2nd – mid of the 3rd centuries AD) belonged. The new portion of the concrete floor had irregular margins and had been partially destroyed by the agricultural activities, because of the scarcity of soil over it. The lower layer of the floor was preserved, consisting of brick and ceramic fragments arranged in close connection with each other and bound with clay mortar, and only in a point, at the western section of the excavation, the higher layer of the floor in concrete, consisting of a mixture of white mortar and brick fragments, was visible. Although we didn’t found more traces of the mosaic, the new portion of the floor confirms the size supposed for the room decorated by the mosaic, which occupied an area of at least 7×6 m.

The concrete floor was isolated and, proceeding towards the east, we didn’t found other structures for a distance of about 6 m, up to the point where there were two brick walls perpendicular to each other. This lack of structures could reveal the existence of an open space lived for a long time, as evidenced by the numerous coins found (1st – 4th centuries AD).

In the eastern part we identified the fragment of a brick floor, consisting of sub-quadrangular bricks. The comparison with similar floorings uncovered in the past at Bedriacum suggests that this new brick floor can be interpreted as an outdoor flooring: the research will clarify whether this structure was destined to a private space (courtyard of a house?) or to a public space (open area between buildings?) and whether it is contemporary to the Domus del Labirinto (first half of the 1st century AD) or later.

The lack of structures in large parts of the excavation allowed us to carry out six small trenches. In this way we achieved the sandy levels of the hill on which Bedriacum was founded, intercepting the traces of a first arrangement of the area dated back to the 1st century BC.
