Slightly north of Gors Fawr, on the south slopes of the Preselis, is a farm called Cwm Garw. By the side of the track leading to the farm buildings stand two stones. Locally they are known as Cerrig Meibion Arthur or The Stones of Arthur's Sons. They stand at map reference SN 118310.
They stand between 7 and 8 feet high so a good deal taller than a man stands, and are markedly wide flat pillars. This shot, looking NNW shows the wide faces with the slopes south of the spur of land south of Carn Sian in the background.
