In 1876, the castle was acquired by Archduke John Salvator of Austria (John of Tuscany) (1852 – ca. 1911), but on October 6, 1889, he renounced his title and connections to the Habsburg imperial house and changed his name to "Johann Orth", the tenth and last child of Grand Duke Leopold II of Tuscany and Maria Antonietta of the Two Sicilies departing for South America in 1890 with his morganatic wife on his own ship, the "St. Margaret". Johann Nepomuk Salvator was presumed lost at sea in 1890, and declared dead in 1911, but his actual date of death is unknown.
