One of the important traces of Roman times in Mevania, within the current city itinerary, is the Roman Public Baths, rediscovered in 1891 and dating back to the 2nd century AD.
All that remains of the thermal complex is the frigidarium, the room characterised by cold-water baths in which to immerse oneself after passing through the other two rooms: the caldarium intended for hot-water baths and steam baths, and the tepidarium intended for warm-water baths and sweating.
Here one can admire the mosaic floor, of the frigidarium room, measuring approximately 81 m2, which has been completely preserved. It is of exquisite and refined workmanship, made of black and white tesserae, and depicts both real sea animals, such as octopuses and dolphins, and fantastic creatures, such as tritons, horses and sea bulls. Recent restorations have revealed traces of the caldarium.
In Roman times, Bevagna boasted a river port directly connected to Rome via the Tiber. Of its ancient structure, found under the former Dominican convent, only a few rooms made of opus mixtum remain today, such as the remains of warehouses and service rooms.
The evidence of the Port gives an insight into the substantial commercial activity of Bevagna during the Roman era. In fact, it was located in the center of the Umbrian Valley and the River Port, adjacent to the Via Flaminia, and it was a point of exchange for the various transport systems.
Another landmark of Roman times is located near the junction of the thistle and the decumanus of the old Via Flaminia and is the Roman Theatre. The layout of the medieval houses that were built on top of it later retained the curvature of a large theatre that rested on the slope of the hill and overlooked the Via Flaminia. Built in the 1st century A.D., significant remains of two ambulatories that served as support for the cavea are visible inside private houses. In one section of the ambulatory today there is a reception structure. Finds from the various sites of Bevanate Romanity are kept in Archaeological Collection at Palazzo Lepri.
