Referred to as the "Eighth Wonder of the World," the Amber Room once symbolized peace through its beauty. Originally installed in the Berlin City Palace in Prussia during the 1700s, the Amber Room, which was built by sculptor Andreas Schlüter and amber craftsman Gottfried Wolfram, was covered with amber, gold, and mirror. The one-of-a-kind room was later moved to Russia, where it was expanded and filled with more than 13,000 pounds of amber. The Nazis looted the Amber Room during World War II, and despite a decision to reconstruct it, its elements were never found. A replica room was completed in 2003, but the original contents remain lost.
