The building was damaged and burned out on 22 October 1943 in a devastating air raid carried out on the orders of Winston Churchill.
In August 1869 a new building for the gallery was designed by Heinrich von Dehn-Rotfelser, architect and professor of architecture at the Academy in Kassel and opened on 28 December 1877.
Dehn-Rotfelser's gallery building had a length of 89.3 m. The width of the pavilions was 24 m, the central block of 22 m. The roof began at a height of 15 meters.
The highlight of the exhibition was the collection of Dutch old masters, works by painters such as Rembrandt, Paul Potter and Philips Wouwerman.
The new museum was opened on 4 September 1976 and included an additional collection of contemporary art works from the 19th and 20th centuries with Romantic and Impressionist paintings by artists such as Carl Schuch, Lovis Corinth and Max Slevogt.
