Main image

An ancient town in the Lazio region of Italy with visible Roman-period ruins near the modern settlement, known in historical sources as Ferentium. It occupies a hilltop position typical of Etruscan and Roman small towns in the area.

The settlement developed in the Etruscan and Republican periods and continued under Roman rule, with public buildings and urban infrastructure added in the Republican and Imperial eras. Over time the town declined and was largely abandoned in the later antique or early medieval period, leaving ruins that have been subject to archaeological investigation.

Situated in central Italy’s Lazio region, the site lies inland within the province that includes Viterbo and the surrounding countryside; it is accessed from nearby modern towns in the province.

  • Excavations: Excavations have revealed large public buildings and a theatre that are accessible for study and occasional visitor access during guided visits or open days.

What to See #

  • Roman theatre: A partially preserved Roman theatre with visible stone seating and stage area that has been subject to archaeological excavation.
  • Archaeological area: General urban remains, including traces of city walls and building foundations, that mark the footprint of the ancient town near the modern locality.
