The Château des Tourelles was built originally in 1196, when Philippe Auguste (Philip II of France), fighting against the king of England, Richard the Lionheart, for possession of Normandy, seized Vernon and made the town a military base. The castle consists of a square tower surounded by four round turrets, the whole edifice rising to a height of twenty metres. It is one of the few castles in France which has been practically unchanged for 800 years. The property of the commune, it has been listed since 1926 as a monument historique by the French Ministry of Culture.
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.
