Roman Wall Surrounding St Cybi's Churchyard is a Romano-British defensive structure located at Holyhead on the island of Anglesey, Wales. The wall dates to the late Roman period, likely constructed during the third or fourth century AD as part of the coastal defence system protecting Roman Britain against maritime raiders. The structure survives as a substantial stone fortification enclosing the churchyard of St Cybi's Church and represents one of the finest examples of late Roman military architecture in Wales. The wall's construction and preservation reflect the strategic importance of this location during the final centuries of Roman occupation, when such coastal forts played a crucial role in maintaining provincial security.
