Hen Domen Mound and Bailey Castle is a motte and bailey fortification located near Montgomery in Powys, Wales, dating to the Norman period following the invasion of 1066. The site comprises a substantial earthen mound surrounded by a bailey with defensive ditches and banks, representing a typical early Norman military response to the conquest and consolidation of Welsh territories. Excavations have revealed evidence of timber structures on the mound and occupation spanning from the late eleventh century through the medieval period, making it an important example of early Norman defensive architecture in Wales. The monument remains substantially intact as an earthwork and provides significant archaeological evidence for understanding Norman military strategy and settlement patterns in the Welsh borderlands.
