The Kaliningrad Regional Museum of History and Arts, originally a Stadthalle (city hall), was planned by Oberbürgermeister Siegfried Körte in 1907 and opened in the Vorder-Roßgarten district in 1912 according to designs by Richard Seel. It included concert halls, a restaurant, and a garden cafe by the Schlossteich. The Königsberger Philharmonie often performed in the 1,600-seat center. The Stadthalle was used as a military hospital during World War I. The building was heavily damaged by the 26 August 1944 Bombing of Königsberg in World War II. After the war it was part of Soviet Kaliningrad.
The former Stadthalle was restored from 1981-86. Since 1991 it has hosted the Kaliningrad Regional Museum of History and Arts. The museum, founded in 1946, previously had multiple locations throughout the city. It includes exhibits on regional nature, archaeology, history, World War II, and post-war Kaliningrad. The museum also has branches in the city and the Kaliningrad Oblast.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
