Postglacially, humans used the entrance throughout the Urnenfeld Bronze
Age into the Hallstadt/La Tène Iron Age, which is documented by pottery shards. The
lower cave entrances were occupied intensively at the Early Medival times during
which the castle was built 30 meters above the cave entrance on the Jurassic dolimite
plateau. From this time period, few animal and human bones such as iron/bone/stone
tools and bone kitchen rubbish and several pottery shards were found on the yard
infront of the today’s cave entrance and the lower cave part entrance areas.
