There is this show on the History Channel called Hunting Nazi Treasure, in which they try to track down priceless works of art that the Nazis looted, which is still missing today.
Last night they talked about the Amber Room and where it might have gone. One theory is that it's still in Russia, in Kaliningrad. That part of Russia was once part of Germany, and the theory is that the Nazis hid it in an underground bunker, as the Soviets approached, and then sealed the bunker off.
There is this fellow who wants to dig the bunker up. However, safety concerns have so far thwarted that effort.
I wonder if the Amber Room is indeed in that bunker.
