Geras Abbey is a Premonstratensian monastery founded in 1153 as a daughter house of Seelau Abbey by Ekbert and Ulrich of Pernegg. It was and settled by canons from Seelau. Geras Abbey was able to survive the reforms of the Emperor Joseph II and the consequent monastery closures of 1783, and remains in operation to this day.
The abbey church is a Romanesque basilica which was reworked in the Baroque style in the 18th century by the architect Josef Munggenast and the fresco painter Paul Troger. Today the abbey is often used as a venue for classical music recitals.
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.
