In page Sauerland:
"Parts of the Sauerland, especially the major valleys in the northwest, represent an old industrial region. The availability of iron ore and the abundance of wood and water allowed iron production long before the Ruhr area industrialisation and the mining of its coal took place.

Warsteiner is Germany's largest privately owned brewery.
