Privernum is described by Livy as a flourishing Volscian site, which was conquered and destroyed by the Romans in the late 4th century BC. The Appian Way passed nearby. The town recovered under the Roman rule, but disappeared after the fall of the Western Roman Empire, probably destroyed by Saracen attacks.

Lay buildings include the Villa Gallio, a residence of Cardinal Bartolomeo Gallio, the Communal Palace (13th century), with the Dolphin Fountain by Giuseppe Olivieri and the Porta San Marco and Porta Posterola, the only remains of the seven gates once giving access to Priverno. Remains of the old Privernum are located outside the town, including parts of the walls, baths, three partician houses and a temple. Here a colossal statue of Tiberius (now in the Vatican Museum) was found in the late 18th century.
