Onnen-Deg Defended Settlement is a prehistoric promontory fort situated in Ceredigion, Wales, occupying a naturally defensive hilltop position inland from the coast. The monument is defined by substantial earthwork defences comprising banks and ditches that exploit the topography to create an enclosed settlement area of archaeological significance. Dating to the Iron Age, the site represents a form of defended habitation typical of upland settlement patterns in prehistoric Wales, where communities utilised elevated terrain to enhance defensive capability. The survival of its earthwork structures provides evidence of settlement organisation and defensive strategy during the pre-Roman Iron Age period in west Wales.
