The Antiquarium houses a selection of materials from some archaeological sites in the Arianese, an area of Irpinia located at the crossroads of natural transit routes from the Campania plain to the Adriatic coast.
The exhibition includes a selection of the materials found in the prehistoric settlement in La Starza di Ariano Irpino, which, from the fifth millennium BC, with brief solutions of continuity, was frequented throughout protohistory up to the threshold of the Iron Age.
One room is dedicated to the Samnite settlement of Casalbore, situated along the Pescasseroli-Candela sheep-track, in which a group of tumulus tombs dating back to the VI century B.C. and a sacred complex in the locality of Macchia Porcara centred on an Italic temple dating back to the III century B.C. have been identified.
For the Roman and medieval period are illustrated the results of the explorations conducted in S. Eleuterio, where a centre (vicus) identified with Aequum Tuticum was found.
