Coal and Iron Ore Workings West of Abergavenny Road, Blaenavon is a post-medieval and modern iron mine protected by Cadw as a scheduled monument. The site exploits the rich mineral deposits of the Pennine and South Wales Middle Coal Measures, which underlie the landscape in undifferentiated form. These Moscovian-age strata comprise mudstone, siltstone, sandstone, coal seams and ironstone bands interlaid with ferricrete, geology that made the Blaenavon area a centre of industrial extraction from the late eighteenth century onwards.
The workings represent the intensive extraction methods developed during the industrial era, when the dual presence of coal fuel and iron ore in adjacent strata enabled integrated iron production. The ferricrete deposits particularly contributed valuable iron-rich material suitable for smelting. The site's designation reflects its significance as part of the broader industrial heritage of the South Wales valleys.
