The 2005 excavations involved two trenches. In trench F the road surface was investigated and it was found that its builders had levelled the terrain by dumping layers of earth and then constructed the roadbed. The fragments of black glaze pottery recovered date the road to the first half of the 3rd century B.C.
Trench S revealed a chequerwork wall and other walls showing various cuts and rebuilds. The discovery of medieval pottery below layers containing several accumulations of coarse ware, black glaze and refined plain buff pottery datable to the 1st century B.C. may indicate interventions to the chequerwork wall in the medieval period which contaminated the earliest levels.
Trench L revealed a well which probably had ritual functions, the presence of Italian sigillata pottery dates it to the Roman period.
The road already excavated in trenches C and F reappeared in trench M, built either with or without side drains and borders consisting of walls or alignments of stones. Italian sigillata was also present amongst the material recovered here.
In room A, trench R revealed a room with an apse and five tombs, of which four had a ridged covering of tufa blocks and one was open. One of the tombs contained small fragments of coarse ware pottery, an architectural terracotta in the form of a palmette, a small illegible bronze coin and a buckle tongue.
Together with the adjoining rooms, Room A was probably used as a sacred enclosure in its last phase. The late burials placed within a structure of Roman date, interpretable as a bath complex, are to be put into relationship with the presence of the nearby church of S. Pietro in Vetere. A mosaic of black tesserae with cruciform geometric decorative motifs in red and white emerged in room A. In the north sector the actual width (80 cm) and continuation of the basalt road was verified (trench N). The material found in the sector east of the road is of Imperial date, whilst that to the west is Republican. It is not possible to prove definitively that the basalt road was constructed in two successive phases, however, its use and abandonment in two different periods seems certain. Trench H involved the brick building situated within the area delimited by the foundations of a late medieval church. In the late antique period the building was altered, giving it a funerary function with “a cappuccino” and “a cassetta” burials placed in the apse. That the structure was re-used for liturgical purposes in the early medieval period is attested by two stone fragments from the first half of the 9th century. (MiBAC)
