Scotland: Towering Ambitions

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.
