Pen-ffordd-goch is a post-medieval and modern iron mine in Wales, protected by Cadw as a scheduled monument. The site exploits naturally iron-rich deposits within the local bedrock, where Pennine Lower Coal Measures and South Wales Lower Coal Measures formations contain interbedded mudstones, siltstones, sandstones, coal seams and ironstone layers. These Westphalian-age deposits accumulated in ancient deltaic environments and include ferricrete—iron oxide-rich material formed by natural weathering and mineral concentration. The landscape around Pen-ffordd-goch bears evidence of the extractive work undertaken here, with patches marking areas where iron and coal were removed from shallow workings. The iron ore deposits made this location economically valuable during the period of industrial expansion, when local resources were increasingly exploited to supply furnaces and forges. Today, the earthworks and disturbed ground preserve a record of these mining activities and demonstrate the relationship between the underlying geology and post-medieval industrial enterprise in Wales.
