About Wheal Martyn
The extensive historic grounds and largely outdoor museum offer a safe space to reflect, soak up the natural environment and enjoy some sense of normality away from crowds of people in a wonderful historic setting. The layout of Wheal Martyn allows for an experience that avoids close contact with other visitors in a natural way that doesn't feel alien.
Dig deep and discover the special ingredient in your everyday life that still shapes Cornwall and the world today - china clay!
Visit the UK's only china clay museum and discover the fascinating story of Cornwall's billion pound, global industry from the heart of Clay Country.
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, and catch a glimpse of modern machines in the working clay pit.
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'.
Wheal Martyn is a dog friendly, indoor and outdoor museum. Explore the indoor Discovery Centre and follow a virtual tour into a working clay pit with family friendly interactive exhibits, film footage, voice recordings, and a making and drawing area.
Explore 26 acres of woodlands, and follow the historic trail to uncover the reasons why Wheal Martyn is a Scheduled Ancient Monument. Get active on the children's adventure trail, wander through the flat rod tunnel and try to locate the secret drum set! See Cornwall's largest working waterwheel in action, and discover the settling tanks, which are now home to an array of wildlife.
