Château du Pailly was built on the site of an older building dating back to the 13th century. That castle had a strategic position in the south of the Champagne region, close to Burgundy. It was ceded by the bishop of Langres to the Saulx family around 1530 and became a rare and emblematic example of the Renaissance in Champagne.
Gaspard de Saulx-Tavannes inherited the Château du Pailly from his father. In 1563, grieving the death of his eldest son, he turned the medieval fortress into a jewel of the Renaissance architecture, as he had been amazed by Italian palaces in his youth.
The Château du Pailly remained in the Saulx-Tavannes family until 1764. Several owners succeeded one another until Jean-François Moreau du Breuil bought it in 1821 and started to restore it. Today it is open to the public.
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.
