No one is quite sure what happened to the Amber Room after the city was attacked. However, three treasure hunters – Peter Lohr, 71, a georadar specialist, Günter Eckardt, 67, a scientist and Leonhard Blume, 73, a homeopath have been on the lookout for it. They believe that they have finally discovered the long-lost Amber Room inside a network of tunnels beneath East Germany!
