Mystery of the Thames-side Villa

Roman remains have been turning up in an Oxfordshire field for decades, where a student in the 1960s believed he had uncovered a Roman mosaic. Is this the site of a lost grand Roman villa? Neil Holbrook takes charge, with contributions from Louise Revell (Roman archaeologist) and Mark Corney (Roman finds expert). Finds include a rare piece of Roman glass, a cheese press and a huge rustic pot from the 4th century. Stewart believes the River Thames used to run much closer to this site during Roman times.
