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

Check out the original Victorian 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. 

Take a stroll 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. Keep an eye out for our exciting activities throughout the year!

Upcoming Events

Celebration Of Light And Clay Event - Thursday 05 December 2019 to Saturday 07 December 2019

China clay mining has transformed St Austell’s landscape dramatically over time. Take pride in your Cornish china clay heritage and explore this transformative effect as the Wheal Martyn clay pit, woodlands and trails undergo a very special transformation of their own.

Follow a beautiful light trail, exploring the changing landscape by torchlight. Encounter natural and industrial features adorned by light in fascinating ways, and look out for four iconic exhibits along the way. See how the latest LED technology, vivid colours and patterned displays create stunning effects on the iconic elements of Wheal Martyn, such as the waterwheel and flat rod tunnel.

Once you reach Pit View, get ready for an awe-inspiring laser light performance, projected onto the unique canvas of Wheal Martyn’s working clay pit.

Follow the path down to an immersive Woodland Wonderland UV experience. Draw with light on glow frames, or sit for a moment on a UV sofa, hung with lights, and consider how ‘black light’ creates the colour around you. See the ethereal glow of UV bubbles floating in the air, and gasp as colours burst and scatter in vibrant displays. Treat yourself to some festive food and drink too!

There will be five bookable time slots per day for the laser show (Thursday 5th, Friday 6th and Saturday 7th December): 5.30pm, 6.00pm, 6.30pm, 7.00pm and 7.30pm.
