Cwm-Clais Castle Mound is a motte situated in Wales, representing a form of early medieval fortification typical of the Norman period. The earthwork consists of a raised mound that would have originally supported a timber palisade and defensive structures, characteristic of motte-and-bailey castle construction employed throughout Wales following the Norman conquest. Though specific details of its original garrison and precise construction date remain uncertain, such mottes generally date from the eleventh and twelfth centuries and served as focal points for territorial control and defence in contested frontier regions. The monument, registered under Cadw's scheduling system as GM289, survives as a landscape feature demonstrating the physical legacy of medieval military architecture in the Welsh countryside.
