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:
The Château Comtal (Count’s Castle) is a medieval castle within the Cité of Carcassonne, the largest city in Europe with its city walls still intact. The Château Comtal has a strong claim to be called a 'Cathar Castle'. When the Catholic Crusader army arrived in 1209 they first attacked Raymond-Roger Trencavel's castrum at Bèziers and then moved on to his main stronghold at Carcassonne.
The castle with rectangular shape is separated from the city by a deep ditch and defended by two barbicans. There are six towers curtain walls.
The castle was restored in 1853 by the architect Eugène Viollet-le-Duc. It was added to the UNESCO list of World Heritage Sites in 1997.
