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’.
