Overview

History & significance

Pen-y-Gaer Camp is a prehistoric hillfort located in Merionethshire, Wales, and forms part of the Iron Age defensive settlement pattern characteristic of the region. The site is defined by substantial earthwork defences comprising ramparts and ditches that enclose the hilltop, typical of hillforts constructed during the later prehistory of Britain. Its strategic position on elevated terrain reflects the defensive priorities of Iron Age communities in Wales, where such fortified sites served as focal points for settlement, resource storage, and territorial control. The monument is recorded under Cadw's Scheduled Ancient Monuments database as MG155, recognising its archaeological significance as evidence of Iron Age settlement and social organisation in medieval and prehistoric Wales.
