The Amber Room was originally a gift from the Prussian King Frederick William to the Russian Tsar Peter the Great in 1716. From the legendary room, whose value is estimated at 125 to 200 million EUR, individual pieces of furnishings worth more than 2 million EUR were already stolen during the war.
Since 1945, the Amber Room is considered lost. Since then, there have been many assumptions and speculations. One fact is certain: After the theft from the Catherine Palace near Saint Petersburg, it was exhibited in the Königsberg Palace (Kaliningrad) from 1941. After a fire, the room was removed in 1944 and taken away in boxes - whether to the castle's cellars or out of Kaliningrad, to abandoned bunkers or mining tunnels in Germany, Poland or Lithuania is uncertain. There is also speculation whether the boxes sank aboard a submarine in the Baltic Sea.
