Next to the beautifully manicured lawns of Whitestaunton Manor in the Blackdown Hills of Somerset lies a patch of muddy weeds. Coins and pottery have been found here, and it is supposedly the site of a Roman villa. But archaeology student Freya Bowles thinks differently. The team first have to remove weeds and tree roots without the use of mechanical diggers, as it's a scheduled monument. They are also extremely limited as to the size of the excavation. Clearly there are Roman remains, but mixed up with Victorian or Edwardian garden features. Gradually the plan of a Roman bath house emerges. The team are joined by mosaic specialist David Neal and buildings historian Jonathan Foyle. Directed by technological historian Robert Spain, they build a full-size replica hypocaust complete with under-floor heating.
