In the present-day Austrian state of Carinthia, the princely family of Khevenhüller-Metsch owns the Renaissance castle of Hochosterwitz, a significant edifice and major tourist attraction.

Her wealth enabled him to acquire a number of properties in Carinthia such as the castles of Aichelberg, Ortenburg, Sommeregg, Hochosterwitz and Landskron as well as the iron mine of Eisentratten near Gmünd.

Styling himself "Freiherr auf Landskron and Wernberg" he made it to Burggrave und Speaker of the Estates, and managed to make the Khevenhüller family one of the wealthiest in the German Reich.

When in the course of the Counter-Reformation Emperor Ferdinand II abolished the nobility's religious freedom in the Habsburg lands, the Protestant members of the Khevenhüller family were forced to abandon their possessions in Carinthia and emigrated to Germany in 1628.

After the king's death the Swedish state was incapable of repaying the loan and compensated the lender with the property of Julita Gård in Södermanland, which remained the residence of his descendants late into the 19th century.
