Huw Stephens begins his history of Welsh art at a burial chamber on Anglesey, showing how it evolved from prehistoric rock carvings into depictions of the human form and the earliest Welsh portraits.

Huw explores how, from the 18th-century, the dramatic landscape of Wales captivated artists like Richard Wilson and JMW Turner, who painted it in ways that changed the course of art history. Huw also discovers Penry Williams's work, a Merthyr Tydfil artist commissioned to paint his home town's vast Cyfarthfa ironworks.

Huw's journey begins at the dawn of the 20th century with the artists who broke with tradition and depicted Wales in radical new ways. He discovers the work of Augustus John, JD Innes, Gwen John, Evan Walters, Cedric Morris, Brenda Chamberlain, Kyffin Williams and post-devolution artists Daniel Trivedy and Bedwyr Williams.
