The monastery, dedicated to the Assumption of the Blessed Virgin Mary, was founded in 1133 by Adalbert of Rohr.
It was dissolved in the secularization of 1803 when the German princes substituted church lands for property they had lost through Napoleon.
The abbey church, dedicated, like the abbey, to the Assumption, contains a high altar, which represents the Assumption of the Virgin in fully three-dimensional sculpture: a "Theatrum sacrum".
After World War II the exiled German Benedictine monks from Braunau Abbey (Braunau is now Broumov in the Czech Republic) were lodged here in part of the east wing.
They gradually re-established their community, acquiring little by little the remaining parts of the entire monastery complex.
