The Rumpenheim Castle goes back to a manor house that Johann Georg Seifert von Edelsheim had built from 1678 onwards. Under Prince Karl von Hessen-Kassel, who resided in Gottorf as governor of the duchies of Schleswig and Holstein and who bought the Rumpenheim fiefdom from Edelsheim in 1768, the ensemble was expanded to a three-wing complex in the years 1787–1788 and the park was also redesigned . Until the middle of the 19th century, the Rumpenheimer Schloss served as one of the residences of the House of Hessen-Kassel, after that it became increasingly rare, and in 1902 it was finally given up as a seat.
After the First World War, the castle came into the assets of the Kurhessische Hausstiftung, but remained largely unused. In the Second World War, the central building of the palace was damaged by bombs in 1943 and partially burned out.
After 1945, refugees were initially accommodated in the castle, but from the 1950s the building remained largely unused and fell into disrepair. The ruins were supposed to be demolished in the 1970s, which prevented a citizens' initiative. Only since 2002 has the castle presented itself again in its historical external appearance. Inside there are now condominiums.
