The Arch of Trajan thumb|Arch of Trajan. The importance of Benevento in classical times is vouched for by the many remains of antiquity which it possesses, of which the most famous is the triumphal arch erected in honour of Trajan by the senate and people of Rome in 114, with important reliefs relating to its history. Enclosed in the walls, this construction marked the entrance in Benevento of the Via Traiana, the road built by the Spanish emperor to shorten the path from Rome to Brindisi. The reliefs show the civil and military deeds of Trajan. A great part of the arch is decorated with scenes in bas relief: particularly the pillars directed to the town represent scenes of peace and military scenes. The two faces of the Arch are identical in the arrangement of the reliefs. That the reliefs are for the most part not merely fanciful, nor chiefly conventional and decorative in theme and treatment, is also clear at first sight. They plainly refer to actual events and actions in the life of Trajan, whose effigy, sometimes decapitated, appears in all but two of them, one of which is the only one on all the Arch that is substantially defective. The height of the monument is of , with an arch of , a structure composed of limestone rocks and a marble covering. The arch was put during the Middle Age in the fenced area of the town, in order to represent the Porta Aurea, on account of its fair proportions and the wealth and excellence of its sculptural adornments.
