Baden-Baden — once known as Aquae Aureliae — has been a popular spa destination for more than 2,000 years, and much evidence of the Roman presence can still be seen at the well-preserved Roman Bath Ruins.
You can easily spot the entrance by the three Roman amphorae suspended above it. The best example is the Soldiers' Bath under the present day Friedrichsbad spa with its ancient floor and wall heating systems.
Another highlight is the two-meter-high Roman wall. Guided tours of the facility and audio tours are available.
