Llangatock Edge is notable as the site of a series of old quarries, established around 1790 and abandoned for nearly a hundred years, remnants of which include excavated rocks, a series of undulating grassy mounds - former spoil heaps - and exposed, cut limestone faces which merge with the natural cliffs .These quarries once served the ironworks of Nantyglo, to which they were connected by a narrow gauge tramroad.
