S15·E1 Gold in the Moat - Codnor Castle, Derbyshire

The crumbling ruins of Codnor Castle are a sad remnant of the imposing home of the De Grey family - knights who saw action in almost every important medieval battle including the crusades and Agincourt. Today Codnor Castle lies in ruins and there's almost nothing known of how it looked in its prime. As the remains above ground get an overdue renovation, the Time Team risk the dangers of hidden mine shafts in the Derbyshire coalfields to dig into the heart of a building that once dominated the landscape to trace the castle's history. It lives up to the team's hopes as they strike gold with a 600-year-old gold noble coin as well as uncovering a huge round tower and, for the first time in the history of the programme, a drawbridge.
