BADEN, or BADEN-BADEN, a town in the grand duchy of Baden, celebrated for its medicinal springs, which rise from twenty-six wells of the warmth of from 110° to 118° of Fahrenheit. This is a place of great resort for company in the summer, as well on account of the baths as for the picturesque scenery of the vicinity. The city contains about 3000 resident inhabitants; but the numbers visiting it in the appropriate season very far exceed the regular population. There are bathing-houses and promenades, conversation and gaming rooms, libraries, and all the other appendages of a fashionable watering place. It is about four miles from the Rhine, in the Black Forest, near an ancient castle with some curious subterranean apartments.
