Arpaia

Arpaia is a town, "comune" (municipality) and former (now titular) episcopal see in the Province of Benevento in the southern Italian region Campania, located about 35 km northeast of Naples and about 25 km southwest of Benevento.
Arpaia borders the following municipalities: Airola, Forchia, Paolisi and Roccarainola.
History.
Arpaia, rather than present-day Montesarchio, is considered to have been the seat of the ancient Diocese of Caudium (circa 400-600). The see was suppressed in 600, but in 1970 it was formally restored as the Latin Catholic titular see of Caudium.
