Castle Field Camp E Of Craig-Llywn is a prehistoric hillfort located in Wales, protected as a scheduled monument by Cadw. The site occupies a hilltop position founded upon bedrock composed of Pridoli rocks—a geological formation of mudstone, siltstone and sandstone laid down in the Pridoli epoch. This solid foundation provided an advantageous base for defensive earthwork construction.
Hillforts of this type typically date to the Iron Age, though some may have origins in the Bronze Age. They were fortified settlements characterised by one or more concentric defensive ditches and banks constructed to enclose domestic and storage areas. The upland location of Castle Field Camp offered natural defensive advantages, with commanding views across the surrounding landscape that would have allowed early inhabitants to monitor approach routes and control local territories.
Today the monument survives as earthwork remains visible in the landscape. Its protected status reflects the site's archaeological significance as evidence of prehistoric settlement patterns, land use and social organisation in Wales. The surviving earthworks, when examined in conjunction with the underlying geological substrate, provide material testimony to early defensive settlement strategies employed across the British uplands during the prehistoric period.
