Why visit

Visit to discover Cornwall's secret

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.

Discover

  • Immerse yourself in the atmospheric grounds of the original Victorian clay works, bursting at the seams with tools, machinery, artefacts and stories. Discover Wheal Martyn’s past life at the heart of this global industry.
  • Hear real life tales of the industry which shaped the landscape and iconic ‘Cornish Alps’, and of the people in mid-Cornwall and beyond, whose lives were shaped by this ‘white gold’.
  • Find out about Cornwall’s largest mining industry, past and present, and catch a glimpse of modern machines in the working clay pit.
  • Find out about Cornish Mining World Heritage
  • Exciting new exhibitions and activities in our brand new exhibition gallery and activities/learning space.

We are an indoor and outdoor museum.

Settling Tanks 

Now home to an array of wildlife, discover the important role these rather curious and beautiful pools played in the china clay industry.

Wagon Huts

Wheal Martyn is home to beautiful vintage vehicles, including a 1934 ERF lorry and 1916 Peerless lorry, used in World War One before coming to Cornwall.

Waterwheels

See Cornwall’s largest working waterwheel in action, and discover how these magnificent feats of engineering, with their associated ‘flat rods’, helped in mining the clay.

‘Billion Pound Boulders’

Discover fascinating examples of local geology from which valuable china clay is ‘unlocked’, as well as a unique example of exposed granite (a designated Site of Special Scientific Interest) which demonstrates a stage of kaolinisation usually only seen underground.

We are dog friendly!

Bring your four-legged friends along.

Enjoy

Woodland Trails

The museum is set within 26 acres of woodlands. Take a stroll along nature trails and woodland walks, and follow the historic trail to uncover the reasons why Wheal Martyn is a Scheduled Ancient Monument.

    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’.
