The Cathedral of Caserta Vecchia is dedicated to the Archangel Michael, the warrior saint who was the protector of the Lombards and later the Normans. Built in the tenth century at the instigation of Bishop Rainulfo, it has a Romanesque floor plan with Siculan-Arab, Apulian and Lombard influences. On the facade, made of tuff rock from Campania, there are three marble doors embellished with zoomorphic sculptures. The interior, divided into three naves, reuses columns from Roman structures.
