Although Bakewell's history is steeped in agriculture, the industrial revolutions had an enormous impact. The antiques and collectables emanating from this rich and varied past place it firmly on the Great Antiques Map of Britain. Tim Wonnacott visits the Bakewell Food Festival in the heart of the glorious Derbyshire Peak District, where locals have brought along their fascinating objects, including Victorian baking tins used by the alleged inventor of the famous Bakewell puddings and antique wall brackets bought from the illustrious Chatsworth House estate. Tim goes deep underground in search of the precious mineral Blue John, which is unique to the area, and investigates the story of a man who revolutionised fishing in the grounds of Haddon Hall.
