The Georgium Castle and its 20-hectare garden are an impressive example of the ideas of the Enlightenment. Prince Johann Georg von Anhalt-Dessau had commissioned the ensemble in 1780.
Today, the castle houses the Anhalt Picture Gallery Dessau, the most important collection of old paintings and graphics in Saxony-Anhalt.
While the permanent collection closed because of an extensive renovation of the castle in early 2021, special exhibitions in the Orangery and the Fremdenhaus are still open to the public.
