Certainly a much-visited cemetery 1800 years ago, today located in the middle of the forest: Houses for the deceased from Roman times.

Mindfulness Point 4: Inspiration - The "Germanen" Bridge

Many years ago it was believed that the release of carbon dioxide was a sign of extinct volcanism. But this is not the case: the molten rock inside the earth (magma) contains, in addition to mineral components, gases such as carbon dioxide, water vapor, sulfur dioxide, fluorine and chlorine. Depending on how warm it is and how much pressure is created, they escape through cracks in the earth's crust. The source of carbon dioxide in the Gelenberg Forest is a Mofette.

Start of the 280 km long "German Volcano Road", which leads to the 39 highlights in the world of the Eifel volcanoes. Hard to imagine what happened here almost 13,000 years ago. In the gently rolling landscape, the roof of a volcanic focus that had formed underground suddenly bursts open. A massive explosion shakes the area, caused by the underground contact of hot gases and groundwater. The volcano throws out huge amounts of ash and pumice.

With a diameter of 100 metres, the Radio Telescope Effelsberg is one of the largest fully mobile radio telescopes on earth.  Since its commissioning in 1972, the company has continuously worked on improving its technology (e. g. B. a new surface of the antenna dish, better receivers for high-quality data, extremely lownoise electronics) so that even today it is still considered one of the most modern telescopes in the world.
