Diocese of Wiener Neustadt

Wiener Neustadt is a titular of the Roman Catholic Church.

It goes back to the sunken Diocese of Wiener Neustadt in Austria, based in the Cathedral of Wiener Neustadt, which was once home to the archdiocese of Vienna as a suffragan. Today's titular Wiener Neustadt, however, is closely linked with the Austrian military diocese, which has its headquarters in St. George's Cathedral Wiener Neustadt.
