No album or calendar of the Nahe is complete without a picture of the
Rheingrafenstein. What other landscape can offer a symbol comparable to the
Rheingrafenstein at Bad Muenster am Stein? The bubbling salt-water springs
there were already used as a "Badebronnen" (bathing spring) before the
year 1500, long before the little city developed into a world famous spa.
Before that, the saltwater was a source of cooking salt. The
extraction of which was carried out in several steps. Although the water
tastes very salty when it emerges from the spring, it actually contains only
1.3 percent of salt. This was too little for direct extraction of it.
Therefore, it was pumped several times through a "graduation house" where it
trickled down the layered spiny walls. Each time the water ran through this
process, a little of it evaporated and the amount of salt contained in it
increased. When a salt content of between 15 and 20 percent was attained, it
was put into extraction pans where it was boiled until the salt crystals were
completely deposited on the bottom.

walls (salt pans) piled up in wooden scaffolding and evaporates in the process.
The resulting brine-saturated air has healing properties.
