Freudenstein Castle history is closely linked to the House of Wettin. After the discovery of silver in Christiansdorf, Margrave Otto II of Meissen had a castle built in 1168 to protect the silver mines. On 31 July 1312 the castle is first mentioned in a record as a Hus ('house'). After 1505 Duke Henry the Pious mainly resided in Freiberg. During his reign, his sons, later the electors of Saxony, Moritz and Augustus, were born at the castle.
The construction of the new castle was begun in 1566 by master builder, Hans Irmisch, under the supervision of Rochus zu Lynar. Its completion in the Renaissance architectural style was finished in 1577. In Thirty Years' War, it formed part of the defensive system of the town of Freiberg, and was occasionally used as a military base. In 1762, in consequence of the Seven Years' War, the interior of the castle was completely wrecked.
When ownership of the property was taken over by the military treasury in 1784, the second major conversion of the Renaissance palace into a magazine was carried out. This involved a major change to the building structure. The Renaissance windows were replaced by small armoury windows. Inside, low armoury floors were built in a simple design. From 1800, it was partly rebuilt into a miners' granary (Bergmagazin). During the Napoleonic occupation in 1813, the castle was used as a hospital for 1,500 wounded.
With the transfer of legal ownership to the town of Freiberg in 1957, it served until 1979 as a granary. In 1973, a youth club opened in the basement. From 1980 to 1990, a heritage organization was based at the castle. In a return to its structural appearance in 1577, the facade of the New House was rebuilt in the Renaissance style under its direction. In 2004, ownership of the castle was given back to the town of Freiberg. Between 2005 and 2008 it was converted as the result of a Europe-wide competition under the direction of AFF Architects Berlin/Chemnitz. This saw the gutting of the Church Wing, in order to house the mining archives. The 'terra mineralia' exhibition was housed in the adjacent Long House.
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.
