Baden-Baden, a town in the duchy of Baden, famous as a summer resort. It lies on the edge of the Black Forest. Though its actual population is only about 16,200, its summer visitors average over 50,000, and many strangers remain through the winter. Its hot springs, which attract many strangers, were known in the time of the Romans, Baden-Baden claiming to have been founded by Hadrian in the 2d century. In laying the foundations of the summer home of the grand duke, the remains of a vapor bath and a dungeon of that period were found. There are thirteen hot springs, with a temperature of 115° to 150°. The chief spring discharges in twenty-four hours about 4,200 cubic feet of water. The water of these springs is useful in skin diseases, gout and rheumatism. The attraction of Baden-Baden used to be its gaming tables, once the most famous in Europe, but now closed, which, besides paying a rent of $70,000, devoted as large a sum to adorning the promenades and public gardens. The scenery is beautiful. The picturesque ruins of the old castle still crown the summit of the Schlossberg, from which is had a fine view of the Rhine valley.
