Yesterday : Time Team
Tony Robinson explores the history of the run-down Scargill Castle in Co Durham, bought as a wedding present by archaeologist Niall Hammond for his wife Caroline. Reputed to be a medieval stronghold for a powerful dynasty in the war between the Scots and the English, nobody is able to say what it looked like in its prime.
Neil Oliver admires ginger seals at Walton-on-the-Naze, while Nick Crane examines the area's fossil record. Miranda Krestovnikoff explores research into the thornback ray on the Thames Estuary and how it aids conservation. The team also visits Felixstowe, the UK's busiest container port, where HM Revenue and Customs uncover a stash of cocaine smuggled among furniture.
