Secrets of Great British Castles
CHANNEL 5, 8PM
New series. Historian Dan Jones explores the turbulent past of six of Britain’s most famous strongholds, beginning by heading to the southeast of England to visit 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.
