English: Tomb of the Unknown Soldier, dedicated to the unknown soldiers who have given their lives for Poland. The monument is the only surviving part of the Saxon Palace that occupied the spot until World War II. Since 2 November 1925 the tomb houses an unidentified body of a young soldier who fell during the Defence of Lwów. At a later date, earth from numerous battlefields where Polish soldiers have fought was added to the urns housed in the surviving pillars of the Saxon Palace.
