Around 4 km. To the west of Paganico are visibile the substantial ruins of a Roman bath building that probably formed part of a very important villa. Up until recent times the area was exploited for the quarrying of silicacious sand, an activity that has gravely compromised the archaeological site.

The excavations of 2004 brought to light two construction phases in the room at the northwest corner of the complex. The first phase, of the early empire, consisted of a rectangular room with a barrel vault. Later the plan of the room was modified with walls in opus incertum, which created a plunge lined with opus signinum.

A second excavation on the south side revealed a structure supported on the exterior by buttresses in opus reticulatum. To the southwest the room has an apse. Further, a series of channels were revealed that brought water to a cistern slightly lower down. In the western sector is a large room, perhaps the calidarium, with a substantial central exedra and a pavement on suspensurae, only partially preserved.
