Site of a grange of Margam Abbey (Nprn132). Earthworks and modern features indicate a banked, sub-oval enclosure, c.150m N-S by 125m, occupying a ledge on a spur of Mynydd Margam.
Earthworks within the enclosure indicate possible building sites, althought the site of the supposed chapel was reported destroyed by a cess-pit (1983).
