Wheal Martyn Trust is a registered, independent charity. The Trust receives only a small amount of public funding and so relies on the income it can generate, grants it can secure and the generous donations from people who want to ensure Wheal Martyn and its collections are preserved and accessible for the enjoyment of the local community and visitors from further afield.

You can help the Trust to care for this remarkable former Victorian clay works, its collections and archives and to develop new and inspiring ways for people to enjoy and learn about Cornwall’s internationally important china clay mining industry. Your gift, however given, can make a real difference.

Founded more than 40 years ago, Wheal Martyn Trust is the only China Clay museum in the world. Located in Cornwall’s Clay Country on the edge of St. Austell, Wheal Martyn preserves the heritage and tells the story of the Cornish china clay industry. As a registered charity, conservation and education are at the heart of all our activities and our aim is to conserve, enhance, restore and interpret the wonderful collections and ancient buildings relating this important part of Cornwall’s industrial heritage.
The museum and wider park are of national importance and include a Scheduled Ancient Monument and Site of Special Scientific Interest. Our wonderful collections are wide ranging and tell the sorry of the china clay industry. Artefacts range from tools and social history items to vintage commercial vehicles, locomotives and rolling stock. In addition to this thousands of documents, drawings, maps and photographs are stored off site but made accessible for research.
Sharing this wonderful place is central to what we do. We run around 40 different educational workshops and we are visited by thousands of school children each year.
We are constantly striving to improve everything we do and have an extensive programme of conservation, documentation, education and exhibitions. Preserving, enhancing and sharing this special place is key to all our activities.
To be able to carry out our work, the Trust relies on our generous supporters. We simply could not survive without you.
