David Dimbleby encounters the grace and elegance of the Georgian terraces of Bath and Bristol, the magnificent country houses of Blenheim and the gardens of Stourhead.
He discovers where the seeds of the Industrial Revolution were sown, in the canals and locks of the West Country and the tin mines of Cornwall. He also travels across Wales to Thomas Telford's Menai Bridge and to Ireland to tell the story of Georgian Dublin.
