Pernegg Abbey was founded as a Premonstratensian nunnery in 1153. It was founded by Ekbert and Ulrich, who also founded the Geras Abbey about 10 kilometres from Pernegg.
Pernegg became a community of canons in 1584. In 1700 it became an abbey but was dissolved in 1783 under the reforms of Emperor Joseph II. In the mid-19th century the premises were acquired by Geras Abbey. Since 1995 they have been used as a retreat and seminar centre for the monastery at Geras.
References: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.
