Cwm-Clais Castle Mound is a medieval motte located in Wales, designated as a scheduled ancient monument under Cadw reference GM289. The earthwork consists of a substantial mound typical of motte-and-bailey fortifications, constructed during the Norman period of Welsh castle development. Such mottes served as defensive strongholds and administrative centres during the medieval consolidation of Norman power in Wales, though detailed historical records specific to this particular site remain limited. The monument survives as a landscape feature demonstrating the widespread adoption of motte construction as a rapid and effective form of fortification across the Welsh marches and inland territories during the eleventh and twelfth centuries.
