The Château des Baux is a fortified castle built during the 10th century, located in Les Baux-de-Provence. Although already inhabited in the Bronze Age, Les Baux-de-Provence did not really start growing until the medieval period. Built in the 10th century, the fortress and the small town it protects were ruled by the lords of Baux for five hundred years, in the thick of the ceaseless conflicts that ravaged Provence. It was also at Les Baux that the most famous minstrels and troubadours of the day sang songs of courtly love to the maidens of the House of Les Baux. In the 15th century, the lords of Baux were superseded by the barons of the Masons des Comtes de Provence. This was a golden age for the Château, before it came under the control of the kings of France.
From the 16th century on, family feuds and wars of religion brought on the decline of the town until the fortress was pulled down in 1633 on the orders of Louis XIII.

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.
