Site of Forge at Llandyfan is a post-medieval and modern iron forge located in Wales and protected by Cadw. The forge exploited the natural resources of its locality, situated on Millstone Grit Group bedrock comprising mudstone, siltstone and sandstone formations laid down during the Namurian period. This geology provided both raw material and building stone suitable for forge construction, whilst the underlying strata held water resources essential for ironworking operations.
The site represents the industrial heritage of the region, where local iron ore deposits and fast-running water from the Welsh landscape enabled metalworking on a commercial scale. The Millstone Grit Group's coarse-grained character made it workable stone for forge structures, furnaces and associated buildings. Such forges formed crucial nodes in the wider metal-working economy of Wales during this period.
Today the site survives as earthworks and structural remains marking an important phase of industrial heritage. Its designation by Cadw recognises the significance of post-medieval and modern iron production in the Welsh landscape, preserving evidence of the technological practices and resource use that characterised metalworking in this region. The surviving physical remains continue to illustrate how local geology, water supply and entrepreneurial activity shaped industrial development.
