Despite the Second World War the castle remained intact, and in 1958 the Hibernia Mining Society bought the property. However, Hibernia was only interested in the grounds, and offered the castle building to all interested parties for free. Because of the responsibility and the expense of maintaining it, nobody wanted to acquire it until 1966, when a certain Karl Kuchenbäcker bought it. Because of years of neglect, the castle had to be completely restored, and to provide money for the restoration Kuchenbäcker opened it to the public.
