Liebenzell Castle is a hill castle above the town of Bad Liebenzell. The fortification was once the most important castle in the Württemberg part of the Black Forest. The castle was built in the 12th century by the counts of Calw. In 1196 the counts of Eberstein were recorded as the castle's owners. From 1220 to 1230 the castle was extended. It was destroyed in the 16th century and in 1692 and rebuilt in 1954.
Today the castle is owned by the International Forum of Liebenzell Castle. It is used as a youth training centre for the Bad Liebenzell International Youth Forum and has a restaurant.
The castle comprises an irregular, pentagonal fortification with a mighty shield wall, into which a square bergfried with a garderobe has been integrated. The great hall (Palas) is decorated with ornamental ogival openings. The six-storey bergfried has a height of 32 metres and has an entrance six metres in height, a wall thickness of two metres and an area of about 9 by 9 metres.
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.
