The ruins of Roman Ferento, ancient Forentum, lie about 9.2 km from Viterbo in northern Lazio along the road to Civita di Bagnoreggio.
A roadside attraction, you can see the excavations of the theater (complete enough to host summer theater), Roman baths, and the major roman road, the Decumanus maximus by stopping your car alongside the theater and entering the excavations after paying a voluntary fee of 5 euro to the archaeological club that keeps the site clean and maintained for visitors. The excavation is but a very small portion of the whole Roman city.
