Guise castle is a medieval fortification in the town of Guise, in northern France. Originally an early medieval wooden motte and bailey castle, it was rebuilt in stone and then massively expanded during the 12th-16th centuries. It was remodelled by Marquis de Vauban in the late 17th century to meet the advances in sIege technology then taking place. Much of the castle was reduced to rubble during the First World War and, from 1952 onwards, it has been undergoing restoration by the Club du Vieux Manoir. Nowadays it is a popular tourist site.
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.
