Around the third quarter of the 12th century Freiherr von Weissenburg donated land along the Simmen river to the Augustinian order for a monastery. The monastery was first mentioned in 1228 along with the surrounding village. In 1368 the Freiherr von Brandis inherited the Weissenburg lands including patronage of the monastery. It continued to expand during the 13th and 14th centuries as nobles donated lands and the monastery bought estates.
The monastery church of St. Mary became the burial church of the Freiherrs. In 1439 the city of Bern acquired the Weissenburg lands including the monastery and the village. In 1486 they forced the monastery to accept the authority of the college of canons of the Cathedral of Bern. In 1528, Bern adopted the new faith of the Protestant Reformation and secularized the monastery. The monastery church became the parish church of newly created parish.

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.
