Cologne has been a bath city for two thousand years: founded as a Roman colony with thermae, revived as a Therme town in the modern era, with the Claudius Therme's mineral springs still working beside the Rhine. The full Cologne catalogue is in the iOS app.
"Cologne's bathing licence was issued by Rome. It has never technically lapsed."
The Romans built Colonia's baths on the Rhine's left bank; the modern city returned the favour with the Claudius Therme, a thermal complex drawing genuine mineral water in the Rheinpark, plus a stock of saunas and municipal baths across the districts. Rhineland sauna culture follows the national rules (textile-free zones, Aufguss ceremonies, long day passes) with a Kölsch-flavoured sociability that makes the rest halls chattier than the German average.
The Cologne venues in the iOS app catalogue the Therme, the city saunas, and the municipal baths with sauna floors. Venue pages note which houses have true mineral-spring water versus heated mains.
Each card links to a full venue page with hours, access notes, type, and editorial context. Cards are ordered alphabetically.
