David Dimbleby travels Britain and through 1,000 years of history to discover the buildings that have made us who we are. In Scotland he visits Stirling Castle, dramatic symbol of the birth of a new country, and the fairytale tower house of Craigevar. He travels to the crofts of the Outer Hebrides, to the castle that inspired Bram Stoker's Dracula, to the sparkling granite city of Aberdeen and to the tenements of Glasgow - home of Scotland's greatest architect, Charles Rennie Macintosh.

David Dimbleby's architectural tour of Britain heads north to Newcastle, home of George and Robert Stephenson, and then west to Manchester, where Dimbleby finds warehouses based on Venetian palaces and a stunning town hall. He explores the sewers that changed the lives of the Victorian poor, the model village of Saltaire, and the grand merchant houses and shopping arcades of Leeds. He ends his journey in Blackpool, where Victorian engineering was put to the serious business of having fun.
