Archaeologists Alex Langlands and Peter Ginn go down a copper mine, just a few hundred yards from their cottage, which was once the major source of Morwhellam Quay's wealth. In the 19th century the largest deposit of copper in Europe was discovered in Devon. And the mining industry made Morwhellham the busiest inland port in Britain. Meanwhile historian Ruth Goodman learns the art of lace-making, visiting the town of Honiton which became world famous for its lace, renowned for its beauty, delicacy and intricacy. Once half the inhabitants of East Devon were lace-makers.
