Château de Larressingle was built in the second half of the 13th century. The second and third floors were added by Arnaud Orthon de Lomagne, Bishop of Condom, between 1285 and 1305. Windows were added at various times in the 15th and 16th centuries, particularly between 1521 and 1545 when extra works were carried out for Monseigneur de Grossolles, including the construction of a hexagonal tower.
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.
