Château de Grand-Rullecourt was built in 1746 by Antoine-Constant de Hamel, next to the previous castle. After the French Revolution, the chateau was sold as a national asset, (Antoine's son having died on the scaffold). His grandson bought it back but couldn't afford to keep it. It later belonged to Captain Wallerand de Hauteclocque, who was killed during World War I. After the war, the property was sold in parts. Today the castle host a B&B.
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.
