Eddie Butler tells the story of Barry and its island in this new series of Welsh Towns, once the biggest coal port in the world and a day trippers' paradise. But there's more to Barry's history than coal wagons and chip shops. Eddie discovers the story of the sixth-century saint who gave the town its name, finds a Tudor mural and hears about the American soldiers who camped there in the lead up to D-Day. He also learns how the series Gavin and Stacey has given Barry a new lease of life.
