The Man Who Bought a Castle - Alderton, Northamptonshire

Derek Batten bought a plot of land advertised as a castle and moat; but there is little sign of a castle other than a tree-covered mound surrounded by a huge ditch. So he has asked Time Team to sort it out. Because the site is a scheduled ancient monument, the team have to get permission from English Heritage for strictly limited excavations. To complicate matters further, Tony has to adjudicate on a long-running boundary dispute. The team is joined by castles expert Philip Dixon. Phil Harding gets kitted-out in chainmail as a Saxon footsoldier, facing a mounted Norman warrior on a Spanish stallion. The site is finally identified as a ringwork castle, built on a previous Saxon structure around the time of the Norman Conquest.
