The Bodvoc Stone now forms part of the Margam Stone Collection (NPRN 94512), housed in the old school house, Margam, but originally stood as a monument stone on one of a line of Bronze Age cairns on Margam Mountain. Its inscription reads; `BODVOCI HIC IACIT FILIUS CATOTIGIRNI PROENPUS ETERNALI VEDOMAVI? ? `[The Stone] of Bodvoc. Here he lies, son of Cattegern [or Cattegirn], and great-grandson of Eternalis Vedomavus?.
The sixth-seventh century stone was defaced with modern graffiti and an OS mark before being moved to the Museum, and now a replica stands in its place.
