A fire destroyed about a third of the palace in December 1913. Only the exterior reconstruction had been completed when the revolution in 1918 resulted in the abdication of the Grand Duke. The castle later became a museum and in 1948 the seat of the state parliament. The German Democratic Republic used the palace as a college for kindergarten teachers from 1952 to 1981. Then it was a museum again until 1993. The Orangerie had been a technical museum since 1961. From 1974 on, some renovated rooms were used as an art museum.
