Felin Wen Tide Mill is a post-medieval and modern industrial monument located in Wales and protected by Cadw under reference AN130. The mill was constructed to harness tidal power, a renewable energy source exploited extensively along the Welsh coast from the medieval period onwards. Built on bedrock of Upper Cambrian metasedimentary rock, including Tremadoc formation dating to the Tremadocian period, the site sits upon ancient geology shaped during the early Palaeozoic era.
Tide mills operated by trapping water behind a dam at high tide, then releasing it through machinery at low tide to power millstones or other industrial equipment. Felin Wen represents the practical engineering knowledge of its builders, who understood the local tidal range and coastal hydrology well enough to construct a functioning mill at this location. The mill would have served a local community, grinding grain or processing other materials essential to the surrounding area.
The monument survives as evidence of Wales' industrial heritage and the ingenuity of rural mill-builders who maximised natural resources. Its protection by Cadw acknowledges its historical significance and the value of preserving structures that demonstrate the relationship between communities and their environment during the post-medieval and modern periods.
