This arguably rather incongruous monument stands just above the minor, gated road traversing the Lliw valley... yet is, as far as I could tell, not visible from it. Not mentioned on the current OS maps, it is, nonetheless, subject to CADW scheduling. According to Coflein:
“Remains of a small cairn situated on a saddle between two local promontories on a NW-SE aligned ridge. The cairn is circular in shape and measures c. 4.2m in diameter. It is shallow in profile and measures c. 0.65m tall”. (F.Foster/RCAHMW 02.10.2006)
Worth checking out in conjunction with the larger monument about a half mile to the NW below Foel Ystrodur Fawr.
