From high up on the rock of Susa, this castle has witnessed millennia of history. In 1046, Countess Adelaïde received here her husband Otto, Count of Savoy, bringing him the dowry of the marquisate of Susa and the county of Torino.
The Castle was presumed to be built in the Middle Ages, this also explains the presence of mullioned windows on the walls, a typical element of that era. Over the years he underwent several restorations, especially in the 18th century, which gave him the present appearance. Today, it houses in its interior the Historical Archives, the Civic Museum and the Library.
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.
