History

Historically, today's territory of the Diocese of Aachen belonged to the Diocese of Liège and the Archdiocese of Cologne. The diocese was first created in 1802, covering the area west of the Rhine formerly belonging to Cologne, as well as parts from the dioceses Liège, Utrecht, Roermond and Mainz. After the first bishop Marc Antoine Berdolet died in 1809, Pope Pius VII refused to commission the successor suggested by Napoleon, Jean Denis François Camus. After the French rulership over the area, the diocese was abolished by the bull De salute animarum of July 16, 1821, and incorporated into the archdiocese of Cologne.

On August 13, 1930 the diocese was re-established by the papal bull Pastorale officii nostri. Joseph Vogt was appointed as its first bishop.

Major Churches

Aachen Cathedral

The principal church of the diocese is the Aachen Cathedral, of which the central part, the Palatine Chapel, was built in 800 under Charlemagne. It was also the first German World Heritage Site, inscribed in 1978.
