The area of the castle park includes the four-storey cube built by Situation Kunst in 2010 and the underground museum built in 2015, which has exhibition rooms covering an area of around 1,500 square meters. In addition to the permanent exhibition, there are always changing exhibitions that are presented here.
The park contains 14 works of art belonging to the genre of concrete art by 7 different artists, which were installed between 1972 and 2015. The park is also home to the 80-hectare Weitmarer Holz forest area and a pond. The paths are well-maintained and there are children's playgrounds and benches that invite you to spend time there.
The ruins of the Sylvester Chapel were renovated as part of the redesign of the park in 2010.
