The Château de la Preuille took its present form in the 13th and 15th centuries. The wide moat defending the northern aspect of the walls and towers indicates its origins as a stronghold. From 1350, the castle was owned successively by the families of Boux, Bastard (1460), Gastiniere (1541), Pâris (including Claude-René Pâris de Soulanges, comte de Soulanges) (1728), and through the late 18th century, the family of D’Nacquart or De Nacquard.
In 1832, Marie-Caroline of Bourbon, Duchess of Berry, visited the château to launch her coup against King Louis-Philippe in order to crown her son Henri, comte de Chambord, the last legitimate Bourbon. The coup failed and Marie-Caroline was arrested.
During the 20th century, the castle was abandoned and was left in a state of disrepair. It was saved and restored by the Fradin family in the 1970s and 1980s. Renovation was continued by the family Ribow between 2003 and 2019.
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.
