Set above and to the approx west of the now derelict farmstead of Lluest Abercaethon, this round barrow, not mentioned upon the 1:50K OS map, is depicted as a ‘Mound’ upon the latest 1:25K.
Coflein has no such reservations regarding classification. A round barrow it is... and I concur. Dimensions are:
“Average 15m in diameter x approx 2m high . Slight hollow in area of centre, in part made by OS datum post, still present (RSJ 2000).”
Note that the ‘OS datum post’ was conspicuous by its absence.
