The amber room was a 180-square-foot (17-square-meter) room, whose four walls wear made of six tons of amber, decorated with jewels. Thw room, which was constructed by prussian king friedrich wilhelm l, took over eight years to construct. It was completed in 1716, at which time it was given to tsar peter the great of the russian empire as a gift. During world war ll, 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. Another possible destination was the ore mountains in germany where the amber room may have been buried in salt mines. The most popular theory, however, is that the amber room was hidden in a lost, undergrond shelter somewhere in the city of konigsberg, germany. The beautiful room has been called the eighth wonder of the world, and historians eatimate that its value today would be around 142 million. The search for the amber room continues to this day.
