Schloss Großkühnau, Neoclassical château in Großkühnau, Dessau-Roßlau, Germany.

Schloss Großkühnau is a neoclassical château in Dessau-Roßlau featuring symmetrical design and clean architectural lines throughout. The estate includes carefully planned gardens with several man-made islands and serves as the headquarters for the Dessau-Wörlitz Cultural Foundation.

Schloss Großkühnau was built in 1754 for Prince Dietrich of Anhalt-Dessau in the late Baroque style, probably by architect Christian Friedrich Damm. In 1780 Prince Albert Friedrich, son of Leopold II, had it partly remodelled in the Neoclassical style, with a garden hall and portals; only the first-floor ballroom received decoration after designs by Friedrich Wilhelm von Erdmannsdorff. From 20 August 1932 it housed a Reich Labour Service school, and since January 1998 it has been the headquarters of the Dessau-Wörlitz Cultural Foundation.

The Kühnauer Park was laid out from 1753 to 1764 by Johann Leopold Ludwig Schoch on the southern shore of the Kühnauer See and on artificial islands in the lake. The landscaped park forms the western boundary of the Dessau-Wörlitz Garden Realm, a UNESCO World Heritage Site. The garden hall and portal designs added around 1780 show the shift toward classicist forms.

The château stands at the northern edge of Großkühnau, south of Kühnauer See, with Kühnauer Park around it. About 300 metres to the north-east, in the Burgwallwiesen meadows, are the remains of the Wallburg Kühnau rampart. The building itself houses the Kulturstiftung Dessau-Wörlitz headquarters, so visits focus on the park and its artificial islands rather than the interior.
