Schwarzenberg Castle was based on a medieval fortification and together with St. George's Church dominates the scene of the large county town of Schwarzenberg.
The castle was probably founded in the 12th century as a fort and was the original base for the settlement of Schwarzenberg and its vicinity. The former castle was given its present appearance by a conversion into a hunting lodge for the Electorate of Saxony from 1555 to 1558. In 1851-52 its keep and south wing were raised and, in 1875-76, an office building extension was added.
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.
