Flat Holm Victorian Rock Cut Defensive Ditch and Rampart is a Victorian defence work located on Flat Holm island in the Bristol Channel, Wales. The earthwork comprises a rock-cut ditch and associated rampart constructed during the nineteenth century as part of Britain's coastal defence strategy against potential invasion. The fortification reflects the period's concern with protecting strategic maritime approaches and represents the application of contemporary military engineering to the island's limited topography. The defensive works remain as evidence of Victorian defensive architecture adapted to an island setting.
