In 1999 the excavation moved to the nearby “podere cimitero”, that is the site believed to be that of the early medieval baptistery and religious complex. Large tracts of the complex’s sub-foundations of stone blocks emerged still in situ. The trench built masonry sub-foundations were formed by an external facing of squared stone blocks and an internal core in opus caementicium. Evidence for the destruction and robbing of this structure was provided by the scatter on either side of the surviving structures of the opus caementicium fill. Taking into consideration the oblique alignment of the structures, the investigation checked the possibility of the existence of this foundation, in antiquity, in the immediate vicinity of the bed of the large meandering canal, a fact which could relate the foundation to a defensive structure, given the thickness of the walls or to the creation of a new embankment. A Roman wall was found north of the trench built foundation, constituted by a substantial foundation of parallelepiped stone blocks, upon which was a wall of sesquipedales; this structure attests that the medieval centre overlies a pre-existing Roman settlement. Near the area of the cult buildings part of the cemetery, which must have developed around them in the early medieval period, was uncovered. Laid directly on the sandy floor of an ancient fluvial rise, the four tombs were simple depositions in graves delimited by small walls made of brick fragments and stones. The skeletons were laid out with care on an east-west alignment but had no grave goods. (MiBAC)
