The Celtic Hole

---

The "Celtic Hole“ provides a window into the prehistoric mining era (approximately 1,000 to 1,800 years before Christ). When modern copper mining began at Mitterberg (Mühlbach am Hochkönig) in 1829, the "Mariahilfstollen“ was initiated. Not far from the entrance, a prehistoric mining tunnel was discovered, leading to the "Keltenloch.“

Until a few years ago, it was possible to descend about 10 meters into the Keltenloch and explore inside. Unfortunately, due to the risk of collapse in the entrance area, it is no longer safe to enter. To get an idea, please refer to the photo with the "Kelten."
