Vorau Priory was founded in 1163 by Margrave Ottokar III. The monastery quickly became an religious and cultural center of Eastern Styria, but it was badly damaged by fires in 1237 and 1384. Vorau was located on the border to Hungary and therefore repeatedly faced military threats. The monastery was fortified and armed in the 1450s to defend the local population. The monastery was rebuilt into the Baroque style in 17th and 18th centuries. The fortifications were demolished and moat filled in 1844.
Vorau monastery was again damaged by fire in 1945 during the World War II. Today it is a conference center and parish church. There is also a notable library containing 40 000 volumes, including 415 manuscripts.
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.
