Castell Cogan is a sub-oval enclosure about 86m north-east to south-west by 76m, defined by double banks and ditches, set upon a prominent ridge-top knoll and resting on steep slopes to the east. On the gentler slopes to the west a possible outer line of ramparts may define an enclosure, roughly 128m across: excavation, 1971, examined two circular structures within the main enclosure and produced some ceramic material, thought to be later prehistoric in date.
