In 2006, UNESCO designated Cornwall and West Devon Mining Landscape a World Heritage Site. In the eighteenth century, Cornwall was one of the country's principal industrial areas. Before the late 1870s, it produced more tin than any other region in the world, and in the early nineteenth century its output of copper was two-thirds of world production. The remains of the mines contribute to a distinctive cultural landscape; more than 200 engine houses survive - the largest concentration of such monuments in the world. This book, and its companion Cornish Mines: St Just to Redruth, is a guide to the best examples of the surviving mines, with stunning photographs and authoritative text.
