Castell Nos is a motte-and-bailey castle located in Glamorgan, Wales, with Cadw scheduled ancient monument designation GM408. The site consists of a substantial earthen motte typical of Norman fortifications established in South Wales during the late eleventh and twelfth centuries. The castle represents the pattern of Norman military expansion into Welsh territory following the Norman conquest, serving as a defensive stronghold in the contested borderlands of Glamorgan. The earthwork remains visible today as a prominent raised mound, characteristic of early medieval castle construction before the widespread adoption of stone masonry in Welsh fortifications.
