Braichgoch Slate Mine, quarry tour and underground adventure
Braichgoch slate mine was a large slate mine located in Corris Uchaf, north Wales. It operated continuously from 1787 until its closure in 1970, apart from a hiatus in the 1900s. Most of the surface workings of the quarry were removed as part of a road widening and landscaping scheme in 1983.
