Already the Romans appreciated the healing effect of hot springs when they laid the foundation of a healthy bathing culture in Badenweiler nearly 2000 years ago. The artesian well gushes incessantly from the depths of the earth and being an acratotherm with its balanced mineralisation it is very agreeable for any need. To the present day the well-preserved remains of the once largest Roman thermal bath north of the Alps prove the antique origins of Badenweiler. Right next to it, the five stars awarded Cassiopeia Thermal Baths continue the long tradition of the history filled spa.
