Lake Toplitz Treasure – Austria
Lake Toplitz once served as a Nazi Naval testing station, and due to an impending defeat also served as a last-ditch-effort-safe. Retreating Nazi troops were seen sinking their treasures into Lake Toplitz as they fled Allied forces near the end of WWII, however the contents of the boxes is unknown.
Researchers believe that anything from gold and silver to priceless works of art may be at the bottom of the lake, and divers are still trying to locate the boxes. Due to large tree trunks trapped midway down the lake’s depth, the excavation process has not yet been successful.
