In 2015 the subtrench has been further extended to the North-East and it has been possible to verify how the large stone-blocks (already identified in the course of the preceding fieldwork season) are in fact part of a rather large pile. These blocks obviously result from the spoliation process and, in their secondary deposition, block a passage, bordered by debris on both sides, that had been cut through the foundation of the theatre’s scaena. This passage features several phases as suggested by the presence of various horizontal contexts. Some other structures have emerged and belong to the lower levels of the foundation: as such, they could be related to a sewer, possibly linked with the linear anomaly we already identified in the course of the 2011 magnetometry and which appears to cut across the theatre itself.

From the point of view of the general architecture of the building, we have identified the remains of the pulpitum along the scaena. Furthermore, we have recovered rests of a floor which gives an idea of the level of the proscaenium. Remains of the painted plaster on the wall of the postscaenium have also been brought to light: it is preserved up to a height of about 30 cm and it appears to have been decorated with bands of different colours (red, yellow and white).

It is clear that after the abandonment of the theatre (a phase whose absolute chronology cannot be defined yet), the area underwent significant transformations (some especially destructive in character) which affected even the foundations. It is not yet possible to provide a sound explanation for these changes and we wait for the study of recovered materials at least to shed light on the chronology. We still have not identified the floor of the orchestra and the limit of the pulpitum towards the cavea, both apparently obliterated by later interventions.
