Louis Spohr
The palace was acquired by the city of Kassel in 1956, and until 1970 it was the home of the Municipal Art Collection. The Louis Spohr museum, closed by the Nazis in 1933, was re-opened in the building in 1967. It included four display rooms and an archive. The displays presented the violinist Louis Spohr and other violinists and violins of the period. In 1972 the Brothers Grimm exhibition was moved to the ground floor of the palace. In 1999 the Brothers Grimm Museum took over the entire building.
