In 2006, the Cornwall and West Devon mining heritage area was recognised by UNESCO as a World Heritage Site. This put the area on a similar status to such sites as Stonehenge, Ironbridge Gorge, the Dorset and East Devon Jurassic Coast, the Great Wall of China, and the Taj Mahal.

Following this successful WHS bid, Cornwall County Council set up the Cornish Mining Attractions Marketing Association, (CMAMA).
Liskeard and District Museum and Information Centre has been inspected and subsequently endorsed as a full member of CMAMA and is now authorised to use the World heritage Site logo in its marketing and and advertising.
