The Kastenhof in Landau an der Isar, which was renovated and converted as part of a museum conversion in the 1990s, was to receive a new permanent exhibition. The exceptional architectural quality of the building required careful handling of the existing building. The exhibition architecture should of course blend in with the location using appropriate materials and material colors. The oak wood - a preferred construction material in the Stone Age - is also a significant medium to make it clear to the visitor that, contrary to the cliché, this was not a lifeless age, but was shaped by an organic reality. Another conceptual focus of the exhibition architecture is the consistent juxtaposition of Stone Age and contemporary exhibits on different levels of the showcases.
