Stand on the cliffs above St Just on a clear day and you can still see the engine houses that did the work, perched like sentries above the Atlantic, smokestacks pointing at the sky. They are roofless now and the boilers are long cold, but in 2006 UNESCO listed them as a single World Heritage Site stretching from the granite cliffs of Penwith all the way east to Tavistock in Devon - ten districts, nearly two hundred square kilometres, a working museum of the industrial revolution before steam came to the cities.

By the 1810s, Gwennap parish alone was producing roughly a third of the world's supply, and Cornwall as a whole supplied two thirds. The crash came in the 1860s, when richer copper was discovered abroad and the price collapsed. Mines piv...

They went where the ore was - Burra in South Australia, Grass Valley in California, Real del Monte in Mexico, the Witwatersrand in South Africa, Butte in Montana, the lead and zinc fields of Wisconsin, the copper m...

The miners hung a sign on the gate that has become famous: "Cornish lads are fishermen / and Cornish ...

Square or rectangular stone buildings with one arched gable end: engine houses. Linear earthworks running uphill across moorland: tramways for ore. Round wa...
