Trecastle Mound and Bailey Castle is a motte and bailey fortification located in Breconshire, Wales, dating to the Norman period following the late eleventh-century conquest and settlement of South Wales. The site comprises a substantial earthen mound surrounded by an outer bailey, representing the characteristic two-part defensive design employed by Norman lords to establish control over newly conquered territory. Its strategic position within the Brecon Beacons region reflects the broader pattern of Norman castle-building in Wales during the expansion of Anglo-Norman lordship. The monument survives as an important example of early Norman military architecture in the Welsh landscape, preserved under Cadw's protection as a Scheduled Ancient Monument.
