Bizeljsko Castle consists of a residential part that forms the centre of the complex and includes a Baroque chapel, and an outer part that served a defensive purpose.
The castle was mentioned for the first time in written sources in 1404. In 1532 the Tattenbachs came to the castle and were in possession of it until 1671. Later the name Windischgraetz was among its famous owners. The oldest parts of the now visible structure dates from the 14th century, and the castle has been rebuilt and extended gradually over the centuries.
The castle preserves the form of Gothic elements, an arched yard and the chapel of St. Hieronymus, dating to the year 1623. The outer defence zone with its wall and towers is partly in ruins. The residential part is comprised of diverse tracts which surround a modest arcade courtyard from the 17th century. Arcades in the inner courtyard are painted and have been partly added on to, though unsuitably.
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.
