Pit prose
The Prosa mine was a brown iron stone entrance on Eisenberg near Windeck - Öttershagen . The corridor was first mentioned in 1884, but is probably a hundred years older due to the technology found.
The reconstructed mouth from the 19th century with a Polish door frame and quarry stone is part of the mining hiking trail at the Silberhardt mine .
