Selsø Renaissance castle was built in 1576 by Corfitz Ulhlfeld and reconstructed in Baroque style in 1734. The castle stayed abandoned since 1829 and in periods used as a grain magazine. In 1972 the restoration of the castle was initiated. The result is that when you visit the castle today, it stands exactly as it did when it was abandoned in 1829 and started to deteriorate. There is, for example, no electricity, water or heating in the castle.
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.
