Badenweiler Roman Baths

Badenweiler, Germany

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.

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 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.

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.

Absolutely loved my time here. The choice of pools/baths/jacuzzis is quite enough and there wasn't too big of a crowd. Good and relatively secure system in the changing rooms and showers. Can get a bit too cold when transferring between spaces.

Nice and pleasant stay as always in the Cassiopeia thermal baths in Badenweiler. Not too big but therefore usually also not too overcrowded. When we've visited the outdoors water jets were inactive (most likely due to CoViD) but one could access all areas that are available. If you're into history there are some Roman baths ruins right next to the recent bath as well as maybe 200-300m away the ruins of a castle.

Apparently a few of the services were missing because of COVID, and this was not clear from the website. Otherwise, a pleasant stay.

Nice, but nothing extraordinary. Friendly staff. Could use some updates to the interior.

Really nice mineral therme located in a small but beautiful and typical german town (Badenweiller) with nice natural surroundings (a castle, the original Roman therme's ruins, cafés, shops, trek paths etc...). It's a very clean place, a bit crowded during the weekend (mostly due to French people who are sometimes rude and noisy compare to German people) but definitely a nice place to rest and relax. They are three pools, two indoors (32 and 34°C) and one outside (32°C), three small jacuzi style pools inside. Other services are available, massage, sauna, restaurant, café. The rates are quite cheap for what's provided, for around 15 Euros, you have access to the three main pools and you can stay as long as you want. I definitely recommend this place

Caerleon Roman Amphitheatre

Built around AD 90 to entertain the legionaries stationed at the fort of Caerleon (Isca), the impressive amphitheatre was the Roman equivalent of today’s multiplex cinema. Wooden benches provided seating for up to 6,000 spectators, who would gather to watch bloodthirsty displays featuring gladiatorial combat and exotic wild animals.

Long after the Romans left, the amphitheatre took on a new life in Arthurian legend. Geoffrey of Monmouth, the somewhat imaginative 12th-century scholar, wrote in his History of the Kings of Britain that Arthur was crowned in Caerleon and that the ruined amphitheatre was actually the remains of King Arthur’s Round Table.

Today it is the most complete Roman amphitheatre in Britain.
