The excavations carried out during the 6th campaign (2021) concentrated on sector II, in particular Rooms N and E, O1, O2, O3, O4.
Room N was connected to rooms G, H, F and I, which were identified during previous campaigns. The complex that is appearing can be provisionally identified as a public building, the nature of which remains to be ascertained. Room N was paved with a mosaic of pink and black tesserae representing mythological figures in a marine landscape. The presence of a finely decorated apse, characterised by a footing with a moulded travertine architrave and lateral jambs with brick pilasters, also supports this interpretation. Room S was certainly connected to room N. The structure, entirely faced with opus signinum, was an above-ground cistern that fed the fountain situated in the apse of the nymphaeum.

The situation in rooms E, O1, O2, O3, O4 merits particular attention. These spaces, quadrangular and similar in size, can be interpreted as a row of small rooms. This system was obliterated in antiquity when the large portico, constituted by corridor L2, was extended during restructuring of the domus. This hypothesis was confirmed by the discovery of the _ opus_ spicatum floor of room E below the structures of the quadriporticus. The restructuring almost halved the size of several rooms.

At present it is difficult to provide a more detailed reconstruction or identify with any certainty the use and function of the structures that emerged. However, the typology and construction of the walls suggests their interpretation as elements belonging to a Roman domus publica situated within a settlement characterised by a long period of occupation.
The preliminary study of the ceramics, glass and coins document occupation between the 3rd century B.C. and the 7th century A.D., A chronological seriation has been defined through this analysis of the finds, making it possible to associate them with the various structures identified.
