 Sinuessa, on the seacoast between the Liris (Garigliano) and the Vulturnus, at the foot of the Mons Massicus, was the last town in Latium according to the official use of the term and was sometimes assigned to Campania, while Suessa was more assigned to Latium.On the other hand, as Nissen points out (Italische Landeskunde, ii.554), the Pons Campanus, by which the Via Appia crossed the Savo some 9 m. SE of Sinuessa, indicates by its name the position of the old Campanian frontier.
