The Bulwarks, Porthkerry is a promontory fort in Rhoose, Vale of Glamorgan, on the southern coast of Wales overlooking the Bristol Channel. It probably dates to the Iron Age and continued to be occupied during the Roman period in Britain. The ramparts and ditches along the west side are well preserved, but the fortifications are heavily overgrown.
