Bärenfels castle, previously known as Steinegg, is located at the entrance to the Wehra valley above Wehr, high up In the Hotzenwald hill. It was built by Vasolt family in 1323-1330. In the 13th century the castle probably passed into the possession of the Barons of Schönau. Later, the ownership passed on to the Markgrafen (earls) von Hachberg They, in turn, let the castle to the Barons of Bärenfels, knights from Basel, after whom the castle is named today. Since the end of the 19th century the Schwarzwaldverein (Black Forest hiking club) has renovated the castle ruins and opened it for visitors. From the top of the tower, which is visible from afar, you can enjoy a great view of the Swiss Jura, the Dinkelberg and the Wiesental.
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.
