Brüder Grimm-Museum Kassel, Literary museum in Kassel, Germany

The Brüder Grimm Museum Kassel was a literary museum in the city of Kassel dedicated to the work and life of the famous fairy tale collectors. The institution displayed manuscripts, personal belongings, and household furnishings from the Brothers Grimm across multiple exhibition floors.

The museum was founded in 1959 as a result of collaboration between the city of Kassel and the Brüder Grimm Society. After more than five decades of operation, it closed its doors on October 31, 2014.

The Brothers Grimm began collecting tales in Kassel in 1807, and the first volume of Children's and Household Tales appeared in 1812 in a print run of 900 copies. The museum displayed the brothers' own annotated copy of the 1812/1815 edition, added to UNESCO's Memory of the World Register in 2005. Temporary exhibitions focused on fairy-tale motifs through book illustrations.

The museum occupied the Palais Bellevue, a three-storey 18th-century building with a steep red-tiled roof and dormer windows. Its historic spiral staircase from 1790 was closed from summer 2006 to spring 2007 because of structural defects, so only the ground floor stayed open; the whole house reopened for documenta 2007 after wooden doors were replaced with fire doors. The building was not officially designated as a museum, and a conversion would have required a second staircase.

The museum housed a vast specialized library containing works from the collection of germanist Ulrich Pretzel, concentrating knowledge about the Brothers Grimm and their era. This focused collection made the institution a major research center for scholars from around the world.
