About
About Wheal Martyn Clay Works
China clay transformed the landscape around St Austell, creating the white “Cornish Alps” and giving work to thousands. Wheal Martyn preserves two Victorian clay works, with waterwheels, settling tanks and drying kilns, alongside a museum telling the story of the industry and its people.
A viewing platform looks over a working modern clay pit, and woodland trails and a nature trail make it a good family day out.
