Polish historian believes old Nazi bunker hides looted Amber Room

WARSAW — A historian in northeastern Poland says the moss-covered ruins of a German World War II bunker may hide Russia’s precious Amber Room, a national treasure that went missing during the war.

The 18th-century Amber Room, made of amber panels and gold leaf, was fitted into Russia’s Catherine Palace near St. Petersburg, where it remained until it was looted by Germany’s Nazis in 1941.
