Tomen y Cefnlloer is a motte situated in Monmouthshire, Wales, forming part of the defensive landscape of the Welsh–Norman borderlands during the medieval period. The monument consists of an artificial earthwork mound typical of motte-and-bailey fortifications, a common castle form erected in Wales and the Marches following Norman expansion in the late eleventh and twelfth centuries. The site demonstrates the strategic settlement patterns employed by Norman lords to consolidate control over conquered Welsh territories, functioning both as a military stronghold and a centre of lordship. Its designation as a scheduled ancient monument reflects its importance as evidence of medieval fortification techniques and Norman–Welsh frontier administration.
