Château de Sainte-Suzanne was a property of the lords of Beaumont, viscounts of Maine, and was built in the 11th century. The most famous event of castle was when it succesfully repelled the conquer attempt of William the Conqueror in 1083-1086.
Installed on a rocky outcrop dominating the Erve valley, the Château de Sainte-Suzanne consists of a triangular courtyard made up of eleven round and square towers, a moat separating it from the medieval town or even a quadrangular keep with three levels near the drawbridge.
As for the dwelling, it reveals an architecture typical of the Henri IV period, at the transition between the Renaissance and the Classical, with a steep roof made of slates from Angers, a facade with bays or even pediments covering the skylights.
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.
