Overview

History & significance

Garn Boduan is a prehistoric hillfort located in Conwy, North Wales, situated on a prominent hilltop that commands views across the surrounding landscape. The site is defended by a series of stone ramparts arranged concentrically around the summit, characteristic of Iron Age fortification practices in Wales, and is likely to date from the later prehistoric period, though the precise chronology remains subject to scholarly interpretation. The defensive earthworks and stone walls indicate its function as a settlement and stronghold, protecting inhabitants and possibly serving as a refuge during periods of conflict in the pre-Roman iron age. The site remains an important example of prehistoric Welsh hillfort architecture and settlement patterns, preserved as a scheduled ancient monument under Cadw's protection.
