Twyn Castell is a motte situated in Glamorgan, Wales, and dates to the Norman period following the late eleventh-century conquest and settlement of south Wales. The monument consists of a prominent earthen mound, characteristic of early Norman fortifications, which would have originally supported a timber or stone superstructure serving defensive and administrative purposes.
