Tips from the Community
Die Wildfrauhöhle auf dem Leißberg ist ein Hohlraum, der sich in Sandsteinen der Tholeyer Schichten gebildet hat. Diese wurden im Perm abgelagert, und sind eher leicht erodierbar. An manchen Stellen kam es jedoch zur sogenannten Verkieselung der Sandsteine: Ebenfalls im Perm kam es in direkter Nähe zu Vulkanismus. Im Zuge dessen drangen quarzhaltige Lösungen in den Sanstein ein und härteten aus. Hierdruch wurde er hart und beständig, so dass der Fels um die Wildfrauhöhle erhalten blieb.

Hidden in the forest – yet so impressive: The lovingly tended Lourdes Grotto is a place of silence and contemplation. Nestled between moss-covered steps and dense greenery, the small chapel seems almost enchanted. 🌸 The magnificent floral decorations, the stone relief, and the Madonna statue create a peaceful atmosphere – a special moment not only for believers. ✨ Tip: The information panel shows that the view and a geologically interesting stone right next to it are also part of the ensemble. Those who pay attention will discover more than just a photo opportunity.

Mithraeum (Latin mithraeum, plural mithraeen) is the name given to the temples of the Mithras cult. Mithraeums were usually built underground or carved into rock. A relatively small cult room was sufficient for the Mithras communities, which had only one to two dozen members. The largest known mithraeum had space for 80 believers. In contrast to Christianity, where larger churches were built in larger communities, in Mithraism the number, not the volume, was increased. At the height of the Mithras cult in the 3rd century, there were supposedly 800 mithraeums in Rome alone. However, since the individual mithraeums were usually not in use for long, this high number says nothing about the number of followers. To date, the remains of over 1000 mithraeums have been archaeologically proven throughout the entire Roman Empire.
