The first thing you see is the beautiful exterior made of red sandstone atop the small hill in the middle of the surrounding garden. The museum itself has some really interesting artefacts from prehistoric times till late roman times. It is not particularly large but that makes it all the easier to visit.
The rooms are well organized in order, and each one has available material botu in German and in English. Because of some special installations oriented to children, it also has some interactive exhibits which can be fun for adults as well!
