The Bunker Museum occupies the command bunker of the German forces that defended Königsberg in April 1945. The bunker is preserved almost exactly as it was when it served as the final headquarters of General Otto Lasch during the siege, and the recreated interiors — operations rooms, communications equipment, officers' quarters — give a vivid impression of those final days. Wax figures in German uniforms stand at maps that show the progressive contraction of the defence perimeter.
The museum does not try to glamorise the German military position — it is fundamentally a Soviet victory monument, and the narrative is firmly about the liberation of the city. But the bunker itself, with its concrete walls, cramped corridors, and working vintage equipment, is genuinely atmospheric. It is one of the best-preserved command bunkers in Europe and one of the most honest ways to engage with the violence at the root of the city's transformation from Königsberg to Kaliningrad.
