Fodor's Expert Review Elisenbrunnen

Southeast of the cathedral and the site of the city's tourist-information center is an arcaded, neoclassical structure built in 1822. The central pavilion contains two fountains with thermal water—the hottest north of the Alps—that is reputed to help cure a wide range of ailments in those who drink it. If you can brave a gulp of the sulfurous water, you'll be emulating the likes of Dürer, Frederick the Great, and Charlemagne.
