In order to bring the ore from the open-cast mine Langenacker near Tetingen down into the valley, a "plan incliné", i.e. an inclined plane with a braking hill, used to be set here. The old brakeman's house and the upper part of the braking hill of the Langenacker open-cast mine in Tetingen have been painstakingly restored and are a real highlight for visitors.
