The Famous Amber Room
Originally constructed in Prussia, the world-famous chamber decorated in amber panels backed with gold leaf was located in Catherine Palace of Tsarskoye Selo near St. Petersburg. During the Second World War, it was dismantled and taken to Königsberg, Germany, to be rebuilt. A reconstruction was installed in Catherine Palace and stayed there between 1979 and 2003. The original room covered more than 55 square meters (590 sq. ft) and contained over 6 tons (13,000 lb.) of amber. The true location of that room remains a mystery until today.
