National Treasures of Wales

Griff begins with the 157 miles of Welsh coastline owned and cared for by the Trust, investigating its roots in Barmouth and discovering how the tiny cove of Mwnt copes with the impact of the modern world.

Griff Rhys Jones visits Plas Newydd on the island of Anglesey, which the Trust acquired in the 1970s. It was once the family home of the Marquis of Anglesey, but now property manager Nerys Jones has to think of new ways to attract visitors.

Griff Rhys examines the management of the Trust's farmland and tenanted farms. Beginning in Pembrokeshire with the Trust's latest bequest, Treleddyd Fawr, Griff discusses the restoration work facing National Trust building surveyor Nathan Goss.

Griff visits one of the grandest restoration houses in Britain to find out why the Trust have taken on what was once known as the most expensive council house in Britain.
