Mynydd y Gaer is a prehistoric hillfort situated in Wales, designated as a Scheduled Ancient Monument under Cadw reference GM084. The site comprises a multivallate defensive structure typical of Iron Age hillforts, with multiple defensive banks and ditches arranged concentrically around the summit. The earthworks demonstrate the sophisticated military engineering employed by Iron Age communities in South Wales, reflecting both the strategic importance of the location and the social organisation required to undertake such substantial fortification works. Dating to the Iron Age period, Mynydd y Gaer would have functioned as a settlement and defensive stronghold, potentially serving administrative, trading, or defensive purposes within the broader territorial landscape of its time.
