The Sarnthein family, which has owned Schloss Schneeberg since 1778, has a long relationship with the Tiroler Landesmuseum Ferdinandeum. From the 1930s, Rudolf Sarnthein was responsible for the museum's Botanical Collections. When he was elected to the museum board in June 1941, he suggested that the objects be stored at his family's castle. The Botanical Collections, some of the Graphic Collections, and the library author and coat-of-arms catalogue were stored from May 1943 to the end of 1945 at Schloss Schneeberg. In October 1945 the museum sent several reminders to the transport company Hueber to return the books from Lichtenwerth as rapidly as possible. By the end of 1945 all of the objects stored in the castle had been returned to the Tiroler Landesmuseum.
