In its current form , the castle was likely begun by the noble house of Wagen as a replacement for Boltežar Wagen 's nearby Lihtenberk Castle , already in disrepair and severely damaged by a major earthquake in 1511 . After the 1630 death of Jurij Wagen , the last member of the family , the castle changed several owners until it was in 1672 finally bought by Johann Weikhard von Valvasor after his return from abroad . Thoroughly renovated , it was furnished with a graphic studio , a library , printing press and collection of curiosities . Due to the enormous cost of issuing Valvasor 's book , '' The Glory of the Duchy of Carniola '' , Valvasor became heavily indebted , and was forced to sell first his valuable library and , in 1692 , his estates . His family moved to Krško , while the castle again changed several owners , the last being the noble family Windischgrätz , who abandoned the castle in 1943 . While its interior furnishings were destroyed or looted , the castle itself survived the war intact and was in its immediate aftermath turned into a military hospital . From 1957 it was occupied by Jesuits , who carried out some preventive maintenance on the structure ; in 1972 , a systematic reconstruction effort began , at first led by the art historian Milan Železnik
