This programme takes Time Team back to the earliest beginnings of the Industrial Revolution in the area now known as the Ironbridge Gorge, in Shropshire. In the village of Leighton the Team is investigating a particularly interesting cellar; the archaeology could take us back nearly 400 years. The cellar, based in a pub, contains the remains of a blast furnace – used for making iron. What more can be discovered about the story of Leighton's lost furnace?
