There has been a mine at Parys mountain for at least 3500 years.

Rowland Pugh, a local miner, discovered the "Great Lode" on 2 March 1768 and was rewarded with a bottle of whisky and a rent-free house for his lifetime. It's heyday was the 18th and 19th Centuries when there where thousands of workers at the site providing most of the worlds copper. The centre of the mountain has been gouged out, and at one point was one of the biggest man made holes.
Parys Mountain dominated the world's copper market during the 1780s, when the mine was the largest in Europe.
