A Survey of Defended Enclosures in Pembrokeshire

Cadw has supported a series of surveys to improve understanding of prehistoric defended enclosures across Wales. Following an initial scoping study by Gwynedd Archaeological Trust, Dyfed Archaeological Trust carried out assessments in Ceredigion (2005–06), Pembrokeshire (2006–07) and Carmarthenshire (2007–08). In Carmarthenshire alone, 214 sites were recorded, including hillforts, promontory forts and smaller defended enclosures, with 46 protected as Scheduled Ancient Monuments. While most of the larger earthworks remain in good condition, many smaller enclosures have deteriorated in recent decades, particularly those only visible as cropmarks. These surveys provide an essential baseline for monitoring and managing some of the county’s most important prehistoric sites.
