Visitors take a journey through the developmental history of our earth in the circular layout. 4.5 billion years can be traced in one day with the help of rocks and fossils. The time calculation of 4.5 billion years here is 24 hours.
The Earth Time Clock in the Geological Teaching Garden shows the visitor the way and integrates him or her into the formation of the Earth: on the clock face, as he or she walks around the central stone, the visitor becomes the hand itself, moving through a period of 4.5 billion years in 24 hours. The history of the earth is divided into the sections prehistoric and early earth ages, earth antiquity, earth middle ages and earth modern times. The segments of the Earth Time Clock, which are extended over 30 m into open space, symbolise the Earth's age. They are paved and walkable with stone slabs and equipped with rocks, minerals and fossils from the respective periods of the earth's history.
The journey through time ends with the last and youngest fossil: the footprint of a child from Nieder-Mörl, which symbolises man's stay on earth lasting only a few seconds. In the Geological Teaching Garden, the viewer also becomes aware of the worthiness of protecting our planet Earth: what was created over billions of years must not be thoughtlessly put at risk in the present generation.
