Kurt-Sauer-Heilquelle is a ferruginous spring named in honour of a notable individual associated with its discovery or promotion, reflecting the German spa tradition of naming mineral sources after physicians, landowners, or benefactors. The iron-rich waters of this spring carry a distinctive mineral character long valued within a thermal tradition for their tonic, invigorating character. The Heilquelle designation underscores the historical esteem attributed to its uniquely mineralised waters.

Insider tip — Kurt-Sauer-Heilquelle (Kurt Sauer Mineral Spring) is an iron-rich mineral spring in the Badenweiler area at the foot of the southern Black Forest, near the Rhine plain that borders Alsace. The reddish iron-oxide deposits around the spring's outflow give it a distinctive appearance, and Badenweiler's Roman baths — discovered in 1784 and among the best-preserved in Central Europe — testify to the long history of water use here. Anton Chekhov spent his final weeks in Badenweiler in 1904, drawn by the mild climate and invigorating waters.
