A sumptuous Art Nouveau bath house built in 1913 over the city's Roman-era thermal springs — gleaming tiles, steam rooms, cold plunges, a Russian-Roman sweat bath, and two hours of pure relaxation. Co-ed and nude; bring a towel. The nearby Kochbrunnen fountain still burbles hot, salty mineral water in the middle of a small square.
