From April 1945 it was involved in an important part of post-war history. At first occupied by Allied troops, it was then used to house international lawyers and journalists during the Nuremberg trials of war criminals. After the trials, the castle served as an American officers' mess and club house until 1953.
Then it stood empty for over 30 years: the Faber-Castell family had little interest in making it their home. However, following nearly three years of inventory work, the public was able to view the interior in 1986, as part of the company's 225-year celebrations. An extensive exhibition told the story of the company, the family and the castle. In the same year, the four-part television series "Fathers and Sons" was broadcast, which had been filmed mainly in the castle with major international actors.
