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.

The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
