The Insterburg Castle is located in Chernyakhovsk, the third biggest city in Russia's westernmost Kaliningrad Oblast. The castle was built by Teutonic Knights in 1336 and has been heavily rebuilt since then. It was severely damaged during an assault in 1945 and in the post-WWII period. In 1997, activists concerned by the plight of the castle pooled their efforts together under the umbrella of the House Castle Foundation and embarked on the amelioration of the territory, organization of the museum exposition and research works. Visitors can watch medieval fencing matches, have a tour around the castle's underground vaults and try ancient crafts.
