Surprisingly, the National Trust started in Wales. Griff Rhys Jones discovers how the Trust deals with the complexities and conflicts involved in looking after some of Wales's best-loved national treasures. He begins with the 157 miles of coastline owned and cared for by the Trust in Wales.

In this programme, he visits Plas Newydd on the island of Anglesey in north west Wales, which the Trust acquired in the 1970s. Once it was the family home of the Marquis of Anglesey, and now property manager Nerys Jones has to think of new ways to attract visitors to this remote location.

The National Trust started in Wales. Griff Rhys Jones examines how it manages its farmland and tenanted farms across the country, beginning in Pembrokeshire with the Trust's latest bequest, Treleddyd Fawr - the most painted and photographed cottage in Wales. Griff discusses the daunting restoration work facing National Trust building surveyor Nathan Goss.

Griff Rhys Jones visits one of the grandest Restoration houses in Britain to find out why they have taken on what was once known as 'the most expensive council house in Britain'. Just off the M4 motorway in south Wales lies the jewel in the crown of Newport - Tredegar House - home to generations of the glittering Morgan dynasty and now a feather in the cap of National Trust Wales.
