After remaining hidden for 180 years, the magnificent Roman Imperial Baths of Baden-Baden have finally surrendered their secrets to modern archaeologists. This extraordinary excavation has unveiled one of Germany’s most important Roman architectural marvels, providing unprecedented insights into the sophisticated bathing culture of ancient Rome.
The Majestic Aurelia Aquensis: Center of Roman Society
The Roman baths of Baden-Baden, historically known as Aurelia Aquensis, were far more than mere bathing facilities. These elaborate complexes served as vibrant hubs of Roman social life where citizens would gather to cleanse themselves, socialize with peers, and conduct important business negotiations.
Built strategically atop the natural hot springs of Florentinerberg, these baths represent an ingenious early exploitation of the region’s geothermal resources. The complex, named in honor of Emperor Marcus Aurelius Severus Alexander Augustus, stood as one of the largest bathing establishments in what is now Baden-Württemberg, demonstrating Rome’s commitment to public infrastructure and community wellbeing.
Treasures Beneath the Modern City
Unexpected Archaeological Findings
Recent excavation work, initially prompted by necessary sewer renovations, revealed remarkably well-preserved Roman structures just one meter below today’s street level. Many of these architectural elements had never before been documented, offering archaeologists fresh perspective on the original design and construction techniques.
Among the most significant discoveries were hypocaust bricks—components of the Romans’ revolutionary underfloor heating system. This ingenious engineering achievement circulated heated air through hollow spaces beneath floors and within walls, creating comfortable temperatures throughout the bathing complex even during harsh German winters.
Glimpses of Imperial Luxury
The archaeological team uncovered screed foundation layers in what appears to have been the bath’s largest chamber. These layers once supported lavish marble cladding that adorned both walls and floors, reflecting the characteristic opulence of Roman bathing culture.
Perhaps most evocative were three perfectly preserved steps leading into an ancient bathing pool—tangible connections to Romans who descended these very stairs nearly two millennia ago. Such physical remnants create a powerful link to everyday life in the ancient empire.
Preservation Challenges and Modern Solutions
The Roman Imperial Baths have suffered considerable damage from urban development over the centuries. Late 19th-century tunnel construction and more recent utility installations have compromised significant portions of the original structure.
Sarah Roth from the State Office for Monument Preservation noted how modern infrastructure has “repeatedly damaged and reduced the structural substance of the Baths beneath the marketplace.” Despite these challenges, the recent excavation—the most extensive in over half a century—has yielded invaluable new information about this ancient architectural wonder.
Cutting-Edge Archaeological Techniques
This excavation represents a milestone not only for its discoveries but also for its methodology. For the first time since the baths’ initial discovery in 1849, researchers employed advanced documentation methods including 3D imaging and CT scanning to create detailed digital models of the site.
These technologies have enabled archaeologists to document the ruins with unprecedented precision, enhancing our understanding of Roman construction techniques and engineering practices that have influenced architectural development for centuries.

A Treasured World Heritage Site
The Roman Imperial Baths received UNESCO World Heritage status in 2021, recognizing their exceptional cultural and historical significance. This prestigious designation acknowledges the site as an invaluable window into Roman engineering, architecture, and daily life.
While many Roman structures across Europe have been lost or severely damaged over the centuries, Baden-Baden’s thermal baths offer remarkable preservation, providing direct insight into Roman society and their innovative approach to public wellness.
Future Research and Enduring Legacy
The recent excavation marks just the beginning of renewed scholarly interest in this ancient site. Researchers plan to continue their investigations, hoping to uncover more about the baths’ layout, function, and significance within the broader Roman community of Aurelia Aquensis.
The rediscovery of Baden-Baden’s Roman Imperial Baths highlights the remarkable achievements of Roman civic engineering. As modern research continues to unveil this site’s secrets, it stands as a powerful reminder of Roman innovation—a civilization that masterfully combined comfort, technology, and luxury in ways that continue to inspire us nearly two millennia later.
