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:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
