Dedicated to John the Baptist, the abbey was founded in 1147 as a Premonstratensian house by Welf VI, third son of Henry the Black, Duke of Bavaria, and brother of Duke Henry the Proud. The first monks and their abbot came from the Premonstratensian Rot an der Rot Abbey. The Romanesque abbey church was dedicated in 1176. Between 1470 and 1491 the abbey buildings were refurbished under Abbot Caspar Suiter in the Late Gothic style. Welf VI and his son Welf VII were both buried here.
