Norman and Medieval Castles - Malton, North Yorkshire

Roman Villa - Netheravon, Wiltshire

Filmed from 2 to 4 August 1996, this episode looks for a Roman villa that was first partially discovered 90 years before by William Hawley. Part of the site - a former army barracks - is covered in concrete, which at least protects what is underneath. But as they don't know exactly where the villa is, it could be a problem for both the diggers and the geophysics team. The team are joined by Duncan Coe (county archaeologist), Mark Corney (Roman buildings expert) and Lindsay Allason Jones (Roman finds). At the end of day two Lindsay supervises an al fresco Roman-style meal. By day three they have the bare outline of a very substantial, high-status building complete with mosaic floors and central heating. But then unfortunately the time runs out.
