Amber Room
In 2004, a lengthy investigation by British investigative journalists Catherine Scott-Clark and Adrian Levy concluded that the Amber Room was most likely destroyed when Königsberg Castle was damaged, first during the bombing of Königsberg by the Royal Air Force in 1944 and then by the Soviets' burning of the castle followed by shelling of the remaining walls. Official assessments, set out in documents from the Russian National Archives written by Alexander Brusov, head of the Soviet team charged with locating the Amber Room following the war, agreed with this theory. The official report stated: "Summarizing all the facts, we can say that the Amber Room was destroyed between 9 and 11 April 1945."
