The Château de Roquefixade is a ruined castle built on a cliff overlooking the village of Roquefixade. There are records of a castle on the site going back to 1180, though the present ruins are more modern. While marketed in the tourist industry as one of the so-called Cathar castles, the ruins are later than this. Despite this, the site did provide a place of refuge for the Cathars at the time of the Albigensian Crusade.
A natural cleft in the cliff face has been filled in by an arch supported by ramparts. The remains of the castle walls cling to the rock, originally circling an impressive keep built at the highest point of the site.
At the end of the 13th century, Roquefixade became a stronghold at the end of a line of royal fortresses built along the Corbières hills, to keep watch on the territory of the Count of Foix. The keep was remodelled in the 14th century, and other alterations were made in the 15th and 16th centuries. The castle survived until 1632 when the French king Louis XIII rested in the area on his way to Toulouse for the execution of the Henri II, Duke of Montmorency who had risen against Richelieu. Louis took the opportunity to order the destruction of Roquefixade, it now serving no purpose and being costly to maintain.
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.
