Schloss Frohsdorf is a castle-like complex in Lanzenkirchen in Niederösterreich and was built 1547–50 out of the ruins of the so-called "Krotenhof".
After similar devastation in the year 1683 it was largely altered and renovated in the style of Baroque architecture. Greatly damaged by the Second World War, the palace was restored between 1968 and 1971 by the Austrian postal service.
