The Märchensee (Fairytale Lake): A Quarry or an Ancient Sacred Site Near Rottenburg, Germany?

Blog Post on https://mystictrails.net/blog/the-mar...
Let's explore the mysterious Märchensee (Fairytale Lake) and its adjacent quarry area near the town of Rottenburg in southwest Germany. The smoothed rock faces, some marked with distinctive hatchings, and the large spoil heaps resembling ancient burial mounds, provoke speculation about whether this was always solely a quarry or potentially a sacred site in ancient times.
The latter is supported by the fact that the Rottenburg area has been densely populated since the Mesolithic period and was later a center for Celts and Romans. The Church has also left its mark in the form of wayside crosses around this place and a pilgrimage route, the Via Sancti Martini, which passes right through here. The hill on which the Märchensee is located is the Pfaffenberg, which means "Priest's Hill". Coincidence?
