Havelberg
Havelberg was a prince-bishopric of the Holy Roman Empire in the Prignitz. In 1337 Bishop Dietrich I Kothe resided at Wittstock, although the cathedral stood at Havelberg.
From 1383 the Holy Blood shrine at Wilsnack became a major pilgrimage site. The bishopric turned Lutheran during the Reformation and passed to the Hohenzollerns in 1554. In 1571 it was secularised and incorporated into Brandenburg.
