When Rome forced the survivors of Velzna (Orvieto) to abandon the destroyed city in 264 B.C. and take over the eastern side of Lake Bolsena a new life began, that of the Volsinii. The new city was positioned on a series of slopes towards the valley of the lake covering an extension of 65 hectares from Meozzetta di Vietena to Poggio Moscini. However, the area was not deserted as the remains on the hills of the following necropoli reveal Civita near the ditch of Arlena, Capriola, Turona, Bucine, Barano; Poggio Sala, Rebuttano e Scopetone (VIII-V cent. B.C.). Research, in particular that of the École Française brought to light traces of a circle of walls (6 km) in square tuff blocks (clearly visible from Poggio Moscini with signs of pit work, III cent. B.C.), two small temples: one in the Poggio Casetta region (erroneously attributed to the god Nortia and today in a likely way to the god Selvans) and at Pozzarello and the remains of the city that in the second and first centuries B.C. became an important Roman centre strengthened by the passage known as the Via Cassia. In the Mercatello region in the Roman houses placed over the modest Etruscan homes there is a vast underground room where followers of the Dionysiac cult gathered which was later dissolved by the Roman Senate in 186 B.C. by the Bacchanal law. The remains of the clay throne of the Dionysiac cult, called "the Panthers" have been preserved together with many others as proof of the long life of the Volsinii and lake area in the Museum near Rocca Mondaldeschi.
