Completion of the excavation of the theatre’s cavea confirmed the existence of a medieval occupation phase. The radial walls appeared intentionally razed to a uniform height, the levels of fill producing a vast quantity of banded pottery and fragments of glazed ware and proto-majolica. Moreover, the floor level was created through the construction of a containing wall along the edge of the cavea reusing fragments of Roman walls. Two small kilns, of medieval date, for the production of tiles and imbrices were identified and excavated.

Immediately below the medieval occupation levels collapses relating to the structure came to light both between the radial walls and in the area south-east of the upper ambulatory. In this area, where the theatre no longer abutted the hillside behind but had an external façade with arches, the excavation uncovered the collapse of the vaults and the floor of the upper ambulatory.

The cavea, excavated down to the level of the dividing wall between the media and summa cavea, was better preserved in the lower part. Although the facings had been completely removed, it was still possible to read the positions of the steps separating the wedge-shaped sectors of the cavea and the sequence of the seating tiers. Also preserved was a floor in limestone blocks from one of the vomitoria opening onto the cavea. Lastly, the excavation brought to light the front part of the vault of the southern parados and the walls flanking it. In particular, in a gap in the opus testaceum masonry of the innermost wall, part of the analemma was identified. Of Republican date, it was faced with large grey tufa blocks showing signs of heavy damage, probably caused when the structure was robbed in the medieval period.
