The five-part series, which started this week on BBC Four, goes behind the scenes at the country's largest non-governmental landowner and custodian of the historic environment. The National Trust aims to trace the organisation's battle to modernise and strike a balance between preservation and public access to the nation's treasures.
One programme follows a tug-of-war over John Lennon's boyhood home, donated to the trust by his widow, Yoko Ono, who is still eager to have a say in its future. Another examines negotiations with pagans and druids as they plan to celebrate a summer solstice at Stonehenge.
The first programme, screened this week, featured the plight of naturists at Studland Bay in Dorset, who feel that the trust is trying to restrict their use of the beach. Diary would have thought that the trust is all in favour of displaying assets.
