When the Romans conquered this region in what is now southwestern Germany, they brought with them their established custom of bathing. Many of the thermal springs that had been used by the Celts became Roman spas. The bath in Badenweiler was constructed in several phases. In the second half of the first century AD, a small building housing two pools was erected. This was later followed by a reception area, changing facilities, the Roman equivalent of a sauna, with two cold pools, and stone terraces.

The Badenweiler Roman bath ruins (Römische Badruine Badenweiler) are among the most significant Roman remains in Baden-Württemberg. To this day, the complex remains the best pre-served Roman spa north of the Alps.
The best preserved bath ruins north of the Alps can be viewed from purpose-built platforms.
Traditional baths with underground heating
The Roman bath ruins have retained their symmetrical structure. The pools for warm and cold water still have their original surfaces. And large parts of the relaxation room and sauna area, which were lined with sandy limestone, also remain. The remains of the hypocaust heating system – a forerunner of today’s underfloor heating provide a further point of interest.
An elegant addition to the surrounding park, the protective structure around the ruins is well worth a visit.
After the fall of the Roman Empire, the distinctive bathing tradition also began to wane. The Badenweiler complex had long been forgotten – until it was rediscovered and excavated by Margrave Carl Friedrich von Baden in 1784. In the late 19 th century, the ancient spa received a more contemporary counterpart: marble Neoclassicalstyle baths that were extensively extended during the subsequent decades. The natural springs, with temperatures up to 26.4 °C, were enjoyed in Roman times and form the basis for Badenweiler’s status as a spa town today. Since 2001, a spectacular, multiple award-winning glass roof, designed by Stuttgart engineers Schlaich, Bergermann und Partner, has protected the historical site.
The permanent exhibition at the bath ruins offers an insightful look at the Roman culture of bathing and provides fascinating facts about the entire complex.
