Coelbren Fort is a Roman auxiliary fort located in Powys, Wales, positioned strategically in the upper Swansea Valley. The fort dates to the late first century AD and formed part of the Roman military infrastructure established during the conquest and consolidation of Wales. Its rectangular plan and defensive ditches are characteristic of Roman military architecture, though the site remains partially obscured by modern land use and vegetation. The fort represents an important example of Rome's systematic occupation of the Welsh interior, controlling routes through difficult terrain and facilitating the subjugation of local populations.
