Roman baths

About the Welwyn Roman baths

Most archaeological finds happen by accident, usually as the result of a construction project. So was the case with the Welwyn Roman baths. While the baths were being excavated, it became apparent that that the A1 - then under constructon - was going to run right through the site. It became a race against time to complete the excavation before the road was due to be started at the site of the remains. An agreement was reached that meant the Roman baths at Welwyn could become something unique. It is probably the only Roman site that is completely encased underground, and under a motorway too.

Welwyn Baths EntranceThe baths were originally built sometime around the early part of the third century AD and remained in use for about 150 years. The baths are basically simple in design and all the rooms, the hot and cold rooms and baths along with the furnace and heating system are clearly displayed. It is possible to walk around the baths and look down from the gantry and follow the path the Romans would have taken through the process of bathing. Also on show are finds from the site and surrounding areas as well as panels explaining the bathing ritual and subjects relating to the site.
