The Amber Room The Amber Room was a 180-square-foot (17-square-meter) room, whose four walls were made of six tons of amber, decorated with jewels.The room, which was constructed by Prussian King Friedrich Wilhelm the First, took over eight years to build.During World War 2, the Nazis found the invaluable room, tore it down, packed it in hundreds of crates, and took it to a destination that has never been discovered.One theory is that it was loaded onto a passenger ship that was sunk by a Soviet submarine.
