An attack by the Saracens in 891, who remained until the end of the 10th century, devastated the country around current Cannes. The insecurity of the Lérins islands forced the local monks to settle on the mainland, at the Suquet (today the old town). Construction of a castle in 1035 fortified the city by then known as Cannes.
The castle was damaged in end of the 16th century and partially demolished in the 18th century. In 1919, the municipality of Cannes acquired all the buildings in order to house its museum. Today the Musée de la Castre hosts 19th-century Riviera landscape art, musical instruments & ethnographical items in a medieval tower.
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.
