Mědník, Mountain summit in the Ore Mountains, Czech Republic

Kupferhübel (Mědník) is a 910-metre skarn hill on the Ore Mountains ridge above the mining town of Měděnec. Its slopes are covered with heaps and funnel-shaped pits from centuries of surface and underground ore working, and a rotunda chapel stands on the summit.

The mountain became important for copper mining during the medieval period and continued to be worked for centuries. A chapel was added in the 1600s, reflecting the miners' need for spiritual places in their working lives.

The Czech name Mědník is a loan translation of the German Kupferhübel, both meaning copper hill after the ore mined here. The summit chapel of the Immaculate Conception, built in 1674, kept its furnishings largely unchanged over the centuries, and the smaller Sacred Heart chapel was added on the slope in 1935.

The summit lies on the ridge of the Ore Mountains above Měděnec, and the Chomutov–Vejprty railway runs around its northern foot. Two show mines, the Mariahilf and Gelobtes Land adits, can be visited in summer. The Mariahilf adit has been closed to visitors since 2012.

On a small area of the hill, around 70 adits and shafts once operated; collapsed portals, funnel-shaped pits and waste-rock heaps still mark the slopes. The summit has had no mountain hut since the Elster-Baude burned on 5 August 1939 and the ruin was later removed.
