Victor Herold edited the records of the Brandenburg Church Visitations during the Reformation period for the Prignitz, the State of Ruppin, the Uckermark and the Mittelmark. After extensive wartime losses, his manuscripts have taken on great value as sources in their own right. This volume includes the cities of Spandau, Potsdam, Nauen, Rathenow, Friesack, Brandenburg (Havel), Treuenbrietzen, and Beelitz along with their surrounding villages.
