Rheumatism, arthritis, respiratory complaints, skin problems – all this and a host of other ailments can, apparently, be cured by Baden-Baden’s mineral-rich spring water. If you’d rather drink the stuff than bathe in it, head to the Fettquelle fountain at the base of a flight of steps near Römerplatz, where you can fill your bottle for free. It might taste like lukewarm bath water but who cares if it makes you feel 10 years younger?
