Tudor Feasts: A dig in Yorkshire uncovers the feasting hall of a Tudor-era aristocrat--and how the feasting and laughter suddenly came to an end. However, a 5,000-year-old stone temple in the Orkneys is more reluctant to reveal why it was abandoned almost overnight. Roberts and Williams also visit an island used by the very earliest Britons, an altar to Jupiter near Hadrian's Wall, and a preserved Viking boat burial.
