Once situated directly on the banks of the Rhine, Brömserburg Castle was owned by the Archbishops of Mainz from the beginning of the 10th to the beginning of the 19th century. During the 12th century they converted the old fortress into a castle residence. With its vaulted ceilings and walls of more than two metres thick, it successfully provided resistance against any attack. One exception was the destruction of the castle’s southeastern part, which was destroyed in 1640 by the Duke of Longueville. The castle was inhabited up until 1937, before be- ing acquired by Rüdesheim’s town council in 1941. Today, the castle houses the extensive collections of Rheingau’s wine museum.
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.
