at the UK's only china clay mining museum

Why visit

Dig deep and discover the special ingredient in your everyday life that still shapes Cornwall and the world today…china clay! It hides in your toothpaste, your paper, your car tyres and even your cosmetics. It’s a billion pound, global industry. We are telling the story of Cornwall’s secret, and the people who brought it to you, from the heart of Clay Country.
