Until its closure for structural reasons in 2009, the building housed a museum devoted to the Grimm Brothers, which has now moved to the Grimmwelt Kassel.

[2] Bellevue Palace was erected in 1714 by the French architect and Huguenot refugee Paul du Ry as an observatory for Charles I (1654–1730), Landgrave of Hesse-Kassel.

[3] From about 1725 on, the palace was used as a residence for members of the Landgrave's court, such as his mistress Barbara Christine von Bernhold (1690–1756).

[5] In 1779, Frederick II opened a public museum of natural history and classical art, the Fridericianum, but kept the royal painting collection in Bellevue palace.

Jacob Grimm, the private librarian of King Jérôme and state auditor, was a frequent visitor.

The Electress Augusta (1780–1841), who was estranged from William II, used it as her town house and summer residence.

[4] From 1933 until the Second World War it was the residence of Philipp, Landgrave of Hesse (1896–1980), during his tenure as President of the Province of Hesse-Nassau.

[10] The palace survived Allied bombing raids during World War II (1939-1945) with little damage.
