7. Anarchy in the UK - Radcot, Oxfordshire

The Team are in Radcot, Oxfordshire, where they hope to uncover a long-lost fortress built in the 12th century during one of the bloodiest episodes of English history. The tiny hamlet of Radcot in Oxfordshire stands on a strategic crossing on the river Thames. Competing armies have fought over control of the crossing from at least medieval times through to the English Civil War.
