The House of Nobility (Riddarhuset, “the House of Knights”) was built in 1641-1672 as a chamber of Estates of the Realm, and as such, a Swedish equivalent to the British House of Lords. After 1866, when the Riksdag of the Estates was replaced by the new parliament, the Swedish House of Nobility served as a quasi-official representation of the Swedish nobility, regulated by the Swedish government. Since 2003, it has been a private institution, which maintains records and acts as an interest group on behalf of the Swedish nobility, with the main purpose to maintain old traditions and culture.
The building design was started by the French-born architect Simon De la Vallée, but was killed by a Swedish nobleman in 1642. The plans were eventually finished by his son, Jean De la Vallée, in 1660. In the 18th century, the building was often used for public concerts. From 1731, public concerts were performed here by Kungliga Hovkapellet. The south end of the building carries the Latin inscription CLARIS MAIORUM EXEMPLIS, after the clear example of the forefathers, and holds a statue of Gustav II Adolph. North of the building is a park in which is a statue of Axel Oxenstierna. The architecture of the old main library in Turku, Finland was influenced by the Swedish House of Nobility.
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.
