This branch of the road courses through a gently rolling upland plain at the foot of the Martani mountain range, an area that had been heavily populated since the middle of the Bronze Age.

A fourth was discovered during agricultural work in the fields by the church of S. Maria in Pantano and is now located in the small museum in the cloister of S. Maria della Pace in Massa Martana[1] The site also appears in the ancient Roman itineraries found on the Vicarello cups, and (possibly) in the Tabula Peutingeriana.

Another ancient inscription, embedded in the gate of Massa Martana, but discovered nearby, mentions work done on a road by the Roman emperor Hadrian.

Apart from the already noted inscriptions, the only evidence of Roman presence on the site was the building of the church of S. Maria in Pantano, which appears to have been built into the ruins of a Roman-period structure.

Other nearby ruins include the viaducts at S. Giovanni de Butris, Ponte Fonnaia and Bastardo, and significant substructures near the train station at Massa Martana Scalo.
