The Roman Theater of Benevento can be dated between the end of the 1st and the beginning of the 2nd century AD, it is located in the western area of the ancient city. The monument, whose cavea measures about 98 meters in diameter, is built in concrete with facing in limestone and brick blocks. The steps and the frons scenae were covered in marble, as well as marble slabs and stuccoes, still partially preserved, decorated the aulae, the two large rooms which, through corridors (parodoi), lead into the orchestra. The cavea, with a semicircular plan, is built on substructures and has three orders: Tuscan, Ionic and Corinthian. Of these, only the lower order is preserved, consisting of twenty-five arches on pillars with Tuscanic half-columns. The arches of the cavea, with a large finished frame, presented as keystones configured reliefs, represented by busts in the lower order and, most likely, by masks in the higher orders. Some of these masks have been reused in buildings in the historic center, where they are still visible. The cavea ended in the upper part with a gallery, in which niches were opened.
