 Jurassic chert tools, which had been manufactured in the Neolithic Age (about 3000 to 2000 BC), were found in the field area "Mittlerer Wasen".The tools found suggest that some the inhabitants of Kohlberg area were pastoralists and some were hunter-gatherers.This also applies to the Hallstatt period (800-400 BC), derived from some grave mounds in the upper Autmut valley.
