Today’s Heiligenstedten Castle was originally a manor house built in 1717, which was severely damaged by a storm tide in 1756. In 1769, Otto von Blome had a building erected that formed the core of the present castle. Changes to the facade in 1851 to 53 resulted in the appearance we know today.
In 1926 the Blome family sold the castle to the state of Schleswig-Holstein and since then it has been used in various ways. First used as a state educational home, during the war as a military hospital, and later as a home for the elderly and nursing home, it is now owned by the architectural designer Manfred Milz.
