The feudal castle of Sancerre was one of the strongest castles of the Middle Ages built in France. It was the seat of Counts of Sancerre. The future king Charles VII and Joan of Arc stayed at the Chateau de Sancerre, which was strategically placed on the border of the "kingdom of Bourges."
The town of Sancerre was formerly fortified. It was built under the castle, closing access to the less steep slope of the mountain. The castle and city walls were demolished in 1621.
Today only the tower, foundations, cellars or parts of walls remains of castle. The location of the old castle is now occupied by a mansion (1874) of Louis XII and a private park, owned by the Company Marnier-Lapostolle.
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.
