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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
