Just north of the ridge summit of Cefn Bryn, there is a neolithic burial ground and curative well called "Arthur's Stone" (Welsh: Maen Ceti).
Its name comes from a legend that King Arthur threw a large stone from Llanelli, which landed on this spot. It is believed that during the Bronze Age Cefn Bryn was used extensively for ceremonies and rituals. Beneath the bracken on the hill over sixty cairns have been discovered.
According to Coxe, there is a second well in the area to visit on Sunday evenings in the summer and pins are offered for cures.
