Benevento (ancient Beneventum) is a town in inland Campania, 50 km northeast of Naples. Originally a Samnite settlement the city became a Roman colony and achieved particular prominence after Trajan's construction in AD 109 of the Via Traiana, which left the Via Appia at the city. The most famous and best-preserved Roman monument in the city is the Arch of Trajan, built to celebrate the opening of this road and dedicated in AD 114.
