In 1904 while in Rome Theodor Kohn had resigned as the archbishop of Olomouc. After his resignation he moved to Rindbach near Ebensee and in October 1904 he moved again to Ehrehnausen in Styria. There he had bought castle Ehrenhausen. Until his death in 1915 he lived there with his secretary Frantisek Botek, Theodor Vavrusa and his servants from Moravia. Kohn has renovated the Eggenberger mausoleum, which was a component of the castle Ehrenhausen, and after his death he was laid to rest there. Kohn's heirs gave the Eggenberger mausoleum to the Land Steiermark.
