Its story

The story of Ahrensburg Castle.

Schloss Ahrensburg, a Renaissance mansion on an island in an artificial pond in southern Schleswig-Holstein, not far from Hamburg, was built after 1585 at the initiative of Peter Rantzau; a fortified mansion on the site had been owned by the church in 1327. Ahrensburg remained with the Rantzau family for seven generations.

From 1759 to 1778 it served as Schimmelmann's summer residence and remained his family's main seat in the 19th century, though only under Ernst von Schimmelmann (1820–1885) did it again become the focus of family life. When the Great Depression hit the family's fortunes, the Schimmelmanns were forced to sell the castle in 1932. It now houses a museum, with its park open to the public.
