Britain’s fascinating history is all around us. Around the UK there are amazing places to visit and incredible ways to uncover the stories of our shared past. Now historian Dan Snow and BBC presenter Sian Williams are bringing this history to life – live to the nation’s living rooms.

Broadcast from Britain’s most striking historical locations, the series throws open the doors to some of the UK’s most exciting venues, including restorations, digs and heritage sites, giving viewers unique access to events happening across the country

Dover Castle is the setting for the opening programme. King Henry II’s magnificent castle will take centre stage as well as the huge array of secret tunnels cut into the White Cliffs underneath it. These tunnels were where the Dunkirk rescue mission was masterminded from and they housed a fully functioning hospital, barracks and secret telecommunications hub.

Dan and Sian are joined by a team of reporters and, throughout the series, by some of the nation’s favourite celebrities who are on hand to share their passion for history and the way we used to live. In a lively mix of film reports, Sheila Hancock, Lenny Henry, Larry Lamb, Gregg Wallace and Ruby Wax reveal some of the country’s most mysterious, surprising and compelling stories.

National Treasures Live is part of BBC Learning’s Hands On History. Details are available at bbc.co.uk/history/handsonhistory.
