The Château de Beaucaire is a ruined castle in the commune of Beaucaire. Existing structures date from the 12th and 16th centuries, with other elements from various times in the Middle Ages.
First built in the 11th century, the castle was torn down on Richelieu's orders. It used to be protected by a wall, the trace of which can still be followed. It includes a strange polygonal tower perched on a rocky spur, the façades dominating the sheer drop, and a fine round corner tower. Once inside the walls, a staircase leads to a small Romanesque chapel with a charming, sculpted tympanum, and then to the musée Auguste Jacquet. The museum has exhibits on the region's archaeology (dating back more than 40,000 years) and popular arts and traditions.
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.
