The ramp in the back is pretty unusual, and I don't know any other modern station in Germany like that.

The park also has an excellent art gallery, perhaps the best in Germany outside the major cities. One particularly interesting part of it is their Rembrandt collection. The prince bought lots of fakes as well as genuine ones, but the museum decided not to keep them all on display, properly labeled. In most cases, it is indeed very hard to tell the difference between the originals and the others, but I found it hard to believe that the landscape paintings could ever have been considered to be by him.
