Our museum

China clay mining has shaped the landscape, lives of people and economy of mid-Cornwall for over 250 years. It is Cornwall’s largest mining industry. A fully Accredited Museum, we are based within two Victorian china clay works, now a Scheduled Ancient Monument. We tell the story of this fascinating industry and the people who worked and lived in the shadows of Cornwall’s iconic ‘white pyramids’.
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.
