About Welwyn Roman Baths
The Welwyn Roman Baths complex houses the remains of a Roman bathhouse dating back to the 3rd century AD.
Originally part of a larger Roman Villa, the Welwyn Roman Baths are housed in a unique environment - an underground chamber built nine metres below the A1(M) motorway.
Excavations took place before the motorway was constructed and efforts to preserve Welwyn Roman Baths resulted in the construction of the chamber and an access tunnel.
Today visitors to Welwyn Roman Baths can view the remains of the small bath complex, information on the Roman approach to bathing as well as an exhibition detailing the history of the site and other relevant archaeological finds from the local area.
