The Mystical West, an enormous area that stretches from Stonehenge in Wiltshire to the furthest tips of Cornwall and Wales, is David Dimbleby's destination for this episode of A Picture of Britain. In his quest to celebrate the British landscape that has inspired artists for the past 300 years, this week David Dimbleby encounters the work of Dylan Thomas, Constable, JMW Turner and many more.
