Secrets of Great British Castles

Dan Jones heads to the south-east of England to explore the turbulent history of Dover Castle. He reveals that Henry II ordered its construction not only as a statement of royal power, but also out of guilt for the murder of Thomas Becket, the Archbishop of Canterbury, in 1170. Dan discovers how a vast network of tunnels was used to defend the castle, including underground barracks built during the Napoleonic Wars and a nuclear bunker created during the Cold War
