Most important is the training of officials for the tax offices. The academy needs lecture and seminar rooms, student and staff residences, a restaurant and a gymnasium. Administration offices and supply facilities are located in adjacent buildings.
The historical palace rooms are used for concerts and other cultural events and seminars. The Jupiter ball room and the main room of the Oranienburg (the pleasure palace) can be rented for formal dinners. Today there is a gourmet restaurant in the basement of the palace - where the kitchen was formerly located.
The chapel is used for weddings. The municipality of Nordkirchen uses one of the corner towers for civil weddings. The tourist office of the municipality is located in the south-east tower.
The orangery is privately owned. High-quality garden furniture can be viewed and bought there.
The gardens and park are the ideal background for open-air concerts and films. In the autumn of 2008 a film on the Krupp family was made there and broadcast in the spring of 2009.
