Some people believe that the Amber Room was destroyed by the bombing and lost forever. However, several other theories have been formulated: that it is still hidden in an underground bunker at Konigsberg, that it is buried in a mine in the Ore Mountains or that it was aboard a submarine or ship in the Baltic Sea that was sunk by the Soviet Navy.
