Volturno River. The Volturno is a river in south-central Italy.
   It rises in the Abruzzese central Apennines of Samnium near Castel San Vincenzo and flows southeast as far as its junction with the Calore River near Caiazzo and runs south as far as Venafro, and then turns southwest, past Capua, to enter the Tyrrhenian Sea in Castel Volturno, northwest of Naples. The river is 175 kilometres long.
   After a course of some 120 kilometres it receives, about 8 kilometres east of Caiazzo, the Calore River. The united stream now flows west-southwest past Capua, where the Via Appia and Latina joined just to the north of the bridge over it, and so through the Campanian plain, with many windings, into the sea.
   The direct length of the lower course is about 50 kilometres, so that the whole is slightly longer than that of the Liri-Garigliano, and its basin far larger. The river has always had a considerable military importance, and the colony of Volturnum was founded in 194 BC at its mouth on the south bank by the Romans; it is now about one mile inland.
   A fort had already been placed there during the Roman siege of Capua to serve, with Puteoli, for the provisioning of the army. Augustus placed a colony of veterans here. The Via Domitiana from Sinuessa to Puteoli crossed the river at this point, and some remains of the bridge are visible. The river was navigable as far as Capua. In 554, the Byzantine general
