About this programme

6/13. Tony Robinson and the team head to the Lake District to look for copper, a forgotten piece of the nation's industrial heritage. There are nearly two dozen old mines across the mountains, some thought to have been established 400 years ago when the valleys would have been studded with workshops, scaffolding and water-powered machines, home to a brave band of Tudor miners. The team battles the rain, wind and dangerously unstable trackways, but the combination of sheer effort and hi-tech kit enables them to access the heart of an old mine.
