Gneisenau Colliery

The Gneisenau colliery was a hard coal mine in the Derne district of Dortmund.
The Tomson-Bock on the former Gneisenau colliery dates from 1885/86 and is considered a gem among industrial historians. The monument, which has now been extensively restored, is the oldest preserved steel headframe in the Ruhr area.
The Gneisenau coal mine, which was at times one of the largest in Europe, closed in 1985 as the penultimate mine in Dortmund. The Tomson trestle and the historicist shaft hall with carriage circulation as well as the double trestle above shaft 4 from 1933 with the two engine houses have been preserved. The monuments are meanwhile defining the city.

Access to the (interior of) the industrial monument is only possible after consultation with the Foundation for the Preservation of Industrial Monuments and History Culture and usually on the Open Monument Day.

The headframes of the Gneisenau colliery can be seen from a great distance.
They continue to remind us of the mining history tradition of the Dortmund-Derne district. The sight of the winding tower between the houses on Altenderner Strasse is still impressive today.

Sinking of the shafts for the Gneisenau colliery began in 1873, but coal production could not start until 1886. A special feature is the construction of the double trestle frame, which went into operation in 1934 for what was then the central shaft. In 1985 coal production was stopped.

There is a memorial nearby to commemorate the prisoners of war and forced laborers killed in the colliery under National Socialism (komoot.de/highlight/958774).
