Kilianstollen Marsberg, Mining adit in Marsberg, Germany
Kilianstollen is a mining adit in Marsberg that extends roughly 380 meters into the mountain. The system shows three connected mining areas, where visitors can still see the dark brown and reddish rock formations that came from copper, manganese, and iron ore deposits.
The first record of this adit dates back to 1842, when miners opened it to extract copper ore. Over the following decades, this site became a center of regional mining activity and shaped Marsberg's economic development.
The adit bears the name of Saint Kilian and was integral to generations of miners working in this region. Local residents view this site as a testament to their mining heritage and visit to connect with their industrial past.
Access is limited and only with a guide to ensure underground safety. Visitors should bring sturdy shoes and a jacket, as it is cooler inside and the ground can be wet.
The inner walls display mineral deposits that shimmer in deep blue and green tones - traces of mined copper that look almost like painted artworks. Alongside these are yellow and orange stains from sulfur and iron deposits, giving the entire setting an otherworldly appearance.
