Amber Room in Catherine's Palace
The Amber Room or Yantarnaya Komnata is a world-famous chamber decorated in amber panels backed with gold leaf and mirrors, located in the Catherine Palace of Tsarskoye Selo near Saint Petersburg. Originally constructed in the 18th century in Prussia.
The Amber Room was looted during World War II by Army Group North of Nazi Germany and brought to Königsberg for reconstruction and display. Its current whereabouts remain a mystery. In 1979, efforts were undertaken to rebuild the Amber Room at Tsarskoye Selo. In 2003, after decades of work by Russian craftsmen and donations from Germany, the reconstructed Amber Room was inaugurated at the Catherine Palace near Saint Petersburg.
Before the room was lost, it was considered an "Eighth Wonder of the World".
