Overview

History & significance

Gilfach Copper Mine is a post-medieval and modern copper mine located in Wales, protected by Cadw under reference CN170. The mine exploited the mineral-rich geology of the Upper Cambrian bedrock beneath the site, which comprises mudstone, siltstone and sandstone of the Tremadocian age. These Tremadoc strata, though not primarily associated with copper deposits elsewhere, provided the geological foundation from which miners extracted copper ore.

The mine represents the industrial exploitation of Wales's metalliferous resources during the post-medieval period and into more recent times. Copper mining in Wales expanded significantly from the sixteenth century onwards, driven by growing demand for the metal in manufacturing, coinage and warfare. Gilfach's survival as a protected monument offers evidence of the mining technology and working practices employed in Welsh copper extraction.

Today the site remains under Cadw's stewardship, ensuring that the physical remains of the mine—including shafts, workings, spoil heaps and associated structures—are preserved for study and public understanding. The monument stands as a record of Wales's industrial heritage and the labour-intensive processes by which ore was won from the ground.
