Tre'r Ceiri Camp is a prehistoric hillfort located near Caernarfon in Conwy, Wales, situated on a prominent hilltop that commands views across the surrounding landscape. The site is defended by a substantial univallate rampart with an external ditch, enclosing an area of approximately two hectares, and has been interpreted as an Iron Age settlement dating to the later prehistoric period. Archaeological evidence suggests occupation and use during the Iron Age, though the precise chronology of construction and habitation remains subject to scholarly debate. The hillfort demonstrates the defensive and social significance of elevated positions in prehistoric Wales, representing the settlement patterns and territorial organisation of Iron Age communities in the region.
