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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
