Ok, so what are they?
The Gwynedd Archaeological Trust lists the 3 arrow stones as being prehistoric but Coflein classifies them as of unknown period.
H.S. (Bill) Chapman has sent me a copy of his interesting article in 3rd Stone Oct-Dec 1998 entitled “’Arrow stones’ and related phenomena: North Wales examples of prehistoric art”. It lists 15 possible sites and draws parallels with markings found elsewhere.
The term arrow stone comes from the idea that the grooves were caused by the sharpening of arrows. This seems implausible but quite what they symbolise, if anything, is unclear. I hope to post some further ideas in the near future.
