    Hiking

    The 30 m deep shaft of the former "Glückliche Elise" ore mine is full to the brim with water. The strong blue color comes from copper vitriol.
    2024: The edges are very swampy and extend into the depths. You have a better position and view from the mountain slope behind it t1p.de/tatpz

    Hiking

    The small, often bluish-tinged pool in the Einsiedlerbachtal (Einsiedlertal) in the Siebengebirge mountains is not a natural pond, but a relic of historic mining. It is the former machine shaft of the "Glückliche Elise" mine. The winding machine once stood there. It brought the ore to the surface via a vertical shaft – at precisely this spot, the pool, which now has a metallic blue shimmer, was formed by silting.

    A brick arch is also said to be visible nearby, part of the mine's washing plant. Unfortunately, I couldn't find this arch.
