It is unknown when Schuttbourg Castle was built, although some sources say it dates back to the 12th century. It was first mentioned in the 15th century. It was the possession of the Lords of Fischbach who later sold it to the Lords of Clerf.
In the beginning of the 20th century it was a ruin. In 1936 it became private property and was rebuilt into a youth hostel, which opened in 1939. In the Second World War the castle was damaged severely during the Ardennes Offensive. In 1950 these damages were repaired.
The castle is now still private property.
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.
