Königsberg Castle (Russian: Кёнигсбергский замок, romanized: Kyonigsbergskiy zamok, German: Königsberger Schloss) was the seat of the grand masters of the Teutonic Order and of the dukes and kings of Prussia in the city of Königsberg (since 1946 Kaliningrad, Russia). The original fortress on the site was built by the Teutonic Knights in the 1250s, then enlarged and rebuilt into a castle over the following centuries. The castle was severely damaged during World War II, although its exterior walls remained structurally intact. The building survived until 1968, when it was demolished by the Soviet government. Königsberg and the surrounding territories of East Prussia had become Kaliningrad Oblast, a part of the Soviet Union, in 1946. The House of Soviets was built where the castle had stood, but the building was never completed and remained unused for decades before it was torn down in 2024.
