A S-bahn ride away from the city center there is a baroque castle which exhibits a Chinoiserie room with a maladie du porcelaine collection of Chinese import ceramics of the Queen of Prussia.
The castle is a sight to see but for me the porcelain collection was worth a trip. The castle is quided by and audioquide in English, room by room.
In the more modestly decorated upper floor there's both Meissen collection of porcelain and a silver collection. The crown jewelry was taken to somewhere else the moment I visited - probably to be conserved or to be exhibited somewhere else.
