John Sergeant finds out what's being done to save some of our best loved heritage at risk. Windmills, wartime defences, seaside landmarks and churches are all part of what makes the East special. But it's a challenge to find a future for old buildings which may have out-lived their original purpose. John Sergeant goes in search of the people who are passionate about our built heritage and finds out how they are saving it. Bawdsey Radar Station in Suffolk just missed out on winning the BBC Restoration programme, in which the audience selected which buildings to support, 10 years ago. We return there to find out if the local community has finally managed to secure its future. John travels to Great Yarmouth in Norfolk to uncover the remarkable story of the Winter Gardens and the ingenious solutions to save it. He also visits Stevens Mill in Burwell Cambridgeshire, where traditional skills and enthusiasm have helped secure a future for an iconic landmark and Clophill in Bedfordshire to see how eco tourism has given a new life to a ruined church.
