There has been a fort in the site of current Altenklingen castle since around 1200. It was owned by the Barons of Klingen until 1395. After the last owner of Klingen family was killed in battle the castle changed hands several times.
Leonard Zollikofer (1529-1587) demolished the old castle and commissioned architect Mathäus Höbel from Kempten im Allgäu to build a new one. Today it is still privately owned by the family.
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.
