The Bishopric of Havelberg was founded in 946, by Otto I, Holy Roman Emperor (then a prince), but the bishop tended to live in either Plattenburg or Wittstock, a few miles north of Havelberg. An early bishop was Anselm of Havelberg. Havelberg is home to a former monastery, now used as the Prignitz Museum, which was established in 1904.
