Michael Portillo journeys from Newcastle up the north east coast to Lindisfarne. He finds out about the world's earliest swing bridge and its inventor, Newcastle engineer Sir William Armstrong, and discovers how the city's Victorian industrial heritage has found a new cultural purpose. From Seahouses by boat, amid puffins and cormorants, Michael goes in search of a darling of the Victorian press who, with her father, rescued nine people from tumultuous seas. On the Holy Island of Lindisfarne, Michael explores the lime kilns and finds out how, in the 7th century, Christianity spread from here across northern England.
