Craig-Gwrtheyrn is a prehistoric hillfort located in Carmarthenshire, Wales, situated on elevated terrain that commands views across the surrounding landscape. The site comprises defensive earthworks typical of Iron Age fortifications, consisting of ramparts and ditches positioned to exploit the natural topography of the location. This monument represents the settlement and defensive strategies employed by Iron Age communities in south Wales during the first millennium before the Common Era. The site's positioning and construction reflect the importance of elevated defensive positions in the prehistoric period, though detailed archaeological investigation would be required to establish precise chronology and developmental phases of occupation.
