Hvedholm Castle near Faaborg on the island of Funen in Denmark was built in the 15th century. It was owned in turn by the Banke, Hardenberg and Brahe families until 1919, when the Danish government presented the then owners with an enormous tax demand, forcing them to sell it to the state for approximately 175,000 Danish kroner. Hvedholm Castle was later returned to the Brahe family, who were considered for generations the rightful rulers of the castle and surrounding villages.
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.
