The Italian Catholic diocese of Rapolla, in Basilicata, existed from the eleventh century until 1528. In that year it was united with the diocese of Melfi, to form the diocese of Melfi-Rapolla.[1]
The Normans took Rapolla from the Greeks in 1042, and fortified it with works still to be seen. The town was an episcopal see, suffragan of the archdiocese of Siponto, in the time of Pope Gregory VII.[2]
