The Welwyn Roman Baths are situated in a small museum underneath the A1 motorway on the outskirts of Welwyn. The baths were discovered shortly before the motorway was built and it was decided to create a sort of vault under the new motorway so that they were preserved. The museum is one room with the remains of the baths in the centre with information around the outside. Entry is £3.50 per adult with children being free. There is plenty of information to explain what life would have been like in Roman times and how the baths were discovered. There are also activities for children (Roman games, colouring, dressing up). There are no toilet or food facilities on site. Well worth a visit but it won't take more than an hour to see everything here.
