The Ancient Baths

Between the 1st and 4th centuries AD, a thriving Roman city flourished here, featuring major thermal bath facilities. These baths, active until the barbarian invasions of the 5th century, experienced a revival at the end of the 16th century thanks to Philippe V de Hanau. He built a bathhouse, tapped the spring, and for the first time analyzed its waters, confirming their therapeutic properties. The Thirty Years' War abruptly ended this revival by destroying the town and the baths.

Today, you can explore these ancient ruins independently and for free using the Via Janus app. Available on smartphones, this augmented reality guided tour offers a 3D reconstruction of the Roman baths. By following the interactions between the two faces of the god Janus, you immerse yourself in Roman bathing practices and discover anecdotes about daily life nearly 2000 years ago.
