Coelbren Fort is a Roman auxiliary fort located in the Brecon Beacons in Powys, Wales, situated strategically in the upper Neath Valley. The fort dates to the late first century AD, forming part of the Roman military infrastructure established during the conquest and consolidation of South Wales under the Flavian emperors. The site preserves earthwork remains of the fort's defensive structures, including sections of the characteristic playing-card shaped plan typical of Roman military installations, with visible traces of ramparts and ditches. Coelbren occupied an important position within the Roman road network connecting major forts such as Neath and Brecon, serving to control movement through the mountainous terrain and facilitate the administration of the surrounding territory during the Roman occupation of Wales.
