National Treasures of Wales S01E04 - Tredegar House

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. But alongside the benefits of running this stunning visitor attraction comes the responsibility of maintenance - as well as a remit to work with the local community who live cheek by jowl with the big house.

Griff investigates how the Trust manages this while also carrying on the painstaking work of unearthing the hidden history of the house and its beautiful gardens.
