What is the amber room?
Three centuries back the Pussian king had a spectacular room created in a palace in Berlin with artwork out of carved amber. It was later given to the Russian court and the Czars had it expanded and installed in a St Petersburg palace.
Hitler’s highly skilled Socialist Labor thieves took the room to Konigsberg (I think) where it vanished at the end of the war. The panels were either destroyed or hidden, no one is sure.
The room has been recreated in Russia in the last 25 years.
