The orangery, once the winter quarters for exotic plants from Schloss Neuhardenberg, forms a unique ensemble with the castle, the coach house, the cavalier houses and the distillery, which was extensively renovated and restored on behalf of the German Savings Banks and Giro Association. The western Kavaliershaus serves as a hotel together with the adjoining coach house, the orangery with the restaurant Kleine Orangerie forms the garden-side connection on the east side, supplemented by a modern hall building for events.
