Sett in the beautiful Loveny Valley on the southern edge of Bodmin Moor, Carnglaze is Cornwall’s only slate mine and as such, played an important part in the mining heritage of Cornwall. It was of course slate that roofed the industrial revolution and the finely laminated, dark blue slate from Carnglaze was extensively used in South East Cornwall and further afield. Find out about the miners’ ingenuity and skills, and how slate roofed the Industrial Revolution. You will go on a self-guided underground tour to learn how the mine was worked, ending at the Underground Lake with its crystal clear blue/green water. Browse the comprehensive collection of minerals mined and quarried in the South West, after which you will descend a flight of 60 steps taking you about 150m into the hillside and 60m below ground.
