The first known owner of Koberg was knight Erik Nipertz in the 15th century. Later it has been owned for example by royal Vasa and Leijonhufvud (Lewenhaupt) families. The oldest eastern part of the castle dates from the mid-1400s, the middle part from 1620s and the western part from the late 1700s. The other estate buildings were built in Neo-Romantic style in 1900-1904. Today Koberg castle is the residence of Princess Désirée, Baroness Silfverschiöld and her husband Baron Nicklas Silfverschiöld.
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.
