The Archdiocese of Bamberg (lat. Archidioecesis Bambergensis) is a diocese of the Roman Catholic Church in Bavaria and is one of 27 Roman Catholic dioceses in Germany. About a third (actually 38.1% in 2006) of the population is Catholic. With 15.6% this diocese has one of higher (relative) numbers of worshippers on Sunday in Germany. It comprises the majority of the administrative regions of Upper Franconia and Middle Franconia, as well as a small part of Lower Franconia and the Upper Palatinate. Its seat is Bamberg. The dioceses of Speyer, Eichstätt, and Würzburg are subordinate to it. The Diocese was founded in 1007 out of parts of the dioceses of Eichstätt and Würzburg. In 1817, the diocese was raised to an archdiocese.
