Werra Potash Mining Museum

The discovery of potassic salts in the valley of the river Werra, about 70 kilometers southeast of Kassel at the border of Hesse and Thuringia, in 1893 promoted the emergence of a still operating mining area with occasionally up to 30 pits and various potash plants processing the raw material to gain high-quality fertilizers and upstream products for further manufacture. The underground extension of the mines matches the urban area of Munich.

The Werra Potash Mining Museum displays the industrial, mining, and social history of potash mining in the Hessian-Thuringian Werra region on 1,000 square meters and is divided into five departments: potash as raw material, geological conditions of the deposit, potash mining, processing and finishing, and mining and social history.
