Possible sub-megalithic chambered tomb, comprising square, cube-like boulder propped at one corner, sited on an outcrop overlooking steep sea-cliffs. If the site has no artificial elements, and instead is a natural occurrence, its likeness to other sub-megalithic tombs in north Pembrokeshire (like the Carn Llidi chambers to the south, NPRN 305392) may yet have made it a focus for prehistoric rituals. Discovered during fieldwork on 7th March 2008.
