The farm Ousbygård was first mentioned in 1405, but the current Osbyholm castle was built in the first half of the 17th century by Lene Ramel. The square-formed castle is surrounded by a moat and there is a rare octagonal tower, which dates from the 1570s. The castle was damaged in the Scanian War (1675-1679).
Captain Georg Christian Cook started the major restoration in 1750s. The castle was enlarged and the interior was decorated in Rococo style. The next reconstruction was made in 1853. Today Osbyholm is privately owned.
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.
