During the 2017 season we continued to explore the amphitheater, west of the bath complex (Area 1), and the plausible residential quarters of the villa (Area 2), ca. 150 m north of Area 1, where rooms decorated with black-and-white mosaics were previously discovered.

In Area 1 we continued to uncover walls that are part of the underground passageway system beneath the arena of the amphitheater. The investigation of these underground rooms and corridors has contined to point to an absence of orthogonal symmetry to the central longitudinal gallery of the building of the kind one would initially have expected. We have also further explored the N-NE area outside the amphitheatre, but no significant data have emerged here so far.

On the other hand, the exploration in Area 2 has confirmed the presence of the hypothesised large circular room (ca. 22 m diameter) with niches. The expansion of the investigation in a new area (saggio P) north of the already-explored trenches that aimed to identify a fourth niche of the circular room, has brought to light also parts of two new portions of black-and-white mosaics.

The decorative pattern of one, at present exposed only minimally, cannot be identified, while the other seems to have covered quite a large surface and presents a vegetal decoration. Moreover, additional portion of walls uncovered here this year seem to be in connection with the ones discovered in 2016 in Saggio G and might be interpreted as a small portico.

Few artefacts were found in Area 1, while in Area 2 we found a high concentration of fresco fragments, for the most part white, but some of these also carry a decorative red band.
