Marienmünster is well known for the former Marienmünster Abbey Church with its organ, which is well worth seeing and hearing. Marienmünster Abbey is a former Benedictine monastery, dissolved in 1803. Founded in 1127, the monastery reached its peak in the 12th and 13th centuries. During the Thirty Years' War, the monastery and the church were badly damaged and had to be rebuilt from 1661 onwards. From 1965 to 2014, Passionists lived there and pastored the surrounding parishes.
