Zeche Karl, Archaeological mining site in Wuppertal, Germany

Zeche Karl was an iron-ore and calamine mine at the western end of today's Galmeistraße in Wuppertal-Langerfeld, near the Langerfeld indoor pool. No surface buildings remain; the brick-lined shaft, 48.3 m deep by survey though documents claim 59 m, was restored in 1991 with a concrete collar holding a glass plate. The shaft, galleries and winzes survive underground as a protected Bodendenkmal.

Galmei mining in Langerfeld is documented since the mid-18th century. In 1835 Friedrich Harkort sought a mining claim for Zeche Karl, granted in 1856. Until closure in 1896 the mine mainly produced brown iron ore.

The name Galmeistraße recalls the zinc ore (Galmei) mined here since the mid-18th century; the mine itself was named Karl. The site is a protected Bodendenkmal, and the restored shaft of 1991, capped with a concrete collar and a glass plate, is the visible marker of the former works.

The site lies at the western end of today's Galmeistraße, near the Langerfeld indoor pool. No above-ground buildings remain; the brick shaft was restored in 1991 and covered with a concrete collar holding a glass plate. The shaft area is a protected Bodendenkmal, so expect to view it from outside rather than enter.

The brick-lined shaft measures 48.3 m by survey, though documents claim 59 m. After restoration in 1991 it received a concrete collar holding a glass plate, the one element a visitor can still see at the western end of Galmeistraße near the Langerfeld indoor pool.
