Carolus-Thermen Bad Aachen

If you're a steam-lover, try this high-tech spa with a venerable history. In Dürer's time there were regular crackdowns on the orgiastic goings-on at the baths. Today taking the waters is done with a bathing suit on, but be aware that the sauna area is a clothes-free zone.
