A tour of the open air exhibition spaces of the museum provides an impressive depiction of prehistoric times. Full-size models of dwellings from the Stone, Bronze and Iron Ages in the castle gardens give an insight into human progress.  From the mammoth hunters’ winter encampment made with wood and leather, which shows how people lived 27,000 years ago, the visit leads on to an Early Stone Age longhouse with a grain field and a well, constructed with Stone Age technology.  Huts from the Bronze Age, a burial mound and a cremation site document the way of life of our ancestors. The huts of the Hallstatt Period illustrate the dwellings in the Age of the Celts, where the different activities of daily life are shown to be already divided up, so that near a dwelling house you can see a smithy, a place for making pottery and a baker’s hut.

The models of dwellings are all based on archaeological finds. The everyday objects inside the buildings are all archaeologically attested.

As of last year, there is also a Celtic shrine in the open air exhibition space. This is based on the remains of the Celtic shrine found at Roseldorf. The reconstruction also includes elements gleaned from shrines found in France. It is an imaginative model of how such a shrine might have looked.
