The small town of Baden, about twenty kilometres south of Vienna, is famous for its sulphur-rich thermal springs. Their medicinal properties were known to the ancient Romans as early as the 1st century BC. In the reign of Emperor Joseph II, Baden became a famous health resort frequented by members of the Court and aristocracy. Their example was soon followed by the bourgeoisie as well. At the beginning of the 19th century, the town was rebuilt in the Biedermeier style according to the concepts of Joseph Kornhäusel, a famous Viennese architect of the period. To this day, the town has retained a certain charm of the memories of the imperial era.
