Discover Cornwall's secret at the UK's only china clay museum, set within 26 acres of atmospheric woodlands. 

Journey through a Victorian china clay works, bursting at the seams with tools and machinery. Explore the real-life stories and tales of the industry which shaped the landscape and lives of people in mid-Cornwall. Find out about Cornwall's largest mining industry, past and present, and catch a glimpse of modern machines in action in the working clay pit. 

Adventure along the nature trails, woodland walks and adjoining 'Clay Trails', scattered with nature and heritage. Why not bring your dog along too? On your way, see if you can find the workers' historic crib hut, view the rather curious settling tanks and beautiful vintage vehicles, and see Cornwall's largest working water wheel.

Explore the interactive Discovery Centre indoors, featuring displays and exhibitions. Test your understanding of local dialects, try your strength against the village tug-o-war team and meet a Victorian kettle boy.

Children can get active on the adventure trail, dive into the dressing up box and let off steam in the play area. Experience our changing creative clay workshops, events, exhibitions and refuel in our café, offering delicious homemade food.
