After discovering a brine 175m below earth surface in 1822, there were big efforts to use the brine as a remedy. However, Baden had no interests in creating a bath in the first time. So there was founded a community to create the "Sophienbad" (named after grand duchess Sophie von Baden) on May 15, 1834. Soon it turned out that the bath was unable to be financed, so it had to be closed. In 1845 the brine bath got opened, increasing its capacity more and more. In 1862 and 1882 a steam bath and brine inhalations were added.
