Baden stands for “bath” in German. The highlight of this resort town is Friedrichsbad, the world famous bathhouse. Over 2,000 years ago, when the town was called Aurelia Aquensis, Romans such as Emperor Caracalla soaked in these medicinal thermal waters. After you enjoy the same elegant and soothing experience, you can tour the Soldatenbad below. These spa ruins date back to the 1st century BC.
