Staufeneck Castle was built in the 12th century by Burggrafen von Staufeneck. In the year 1307 the castle went into the ownership of the Erzstift Salzburg, under whom it served as one of the maintenance courts in Rupertiwinkel from 1365 to 1805. In 1503, the castle was under Archbishop Leonhard von Keutschach who fundamentally transformed it, giving it its present appearance. Since 1894, the castle has been under private ownership. In the 20th ceuntry, the castle housed a museum. After a complete renovation, it is once again inhabited.
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.
