Sirhowy Ironworks, Site of is a post-medieval and modern industrial monument in Wales, protected by Cadw under reference MM185. The site exploits the rich mineral resources of the underlying Westphalian geology, where Pennine and South Wales Lower Coal Measures Formation bedrock contains mudstone, siltstone, sandstone, coal, ironstone and ferricrete. These geological conditions provided the essential raw materials for ironworking: coal for fuel and smelting, and ironstone for ore. The proximity of these resources in a single location made the site economically viable for the development of iron production during the post-medieval period and beyond. The combination of accessible fuel and iron ore within the local bedrock shaped the industrial character of this Welsh landscape.
