Château du Bousquet was built in the 14th century. Today it hosts a museum of ancient art from the Middle Ages to the present day. The castle has very well-preserved sample of late medieval architecture (furnished interior, furniture, objects, paintings).
The castle, which belonged for four centuries to the Roquefeuil-Blanquefort family, comprises six towers (two hexagonal in the middle of the two front and rear facades, four rounds at each corner). The central tower of the south facade, which contains the staircase is pierced on the ground floor of a radiating Gothic door. The typically feudal and defensive character of the castle is somewhat mitigated by the existence of later windows on the three floors. The defensive system which surrounded it (enclosure, ditch, fortifications) disappeared, replaced by two wings in the 17th century. Inside, the ground floor has kept its kitchen intact, with the mesh stage where the musicians were based. The chapel retains a decoration painted by Debert in 1709.
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.
