Talk:Penrhos Feilw Standing Stones

Stone source
Are these stones there naturally, ie, is there a stone base in the ground they are part of, or were they quarried from a nearby source and moved there, being placed there on purpose? — Preceding unsigned comment added by 2600:8805:5805:A00:D8F4:17A2:E3F3:B0E7 (talk) 11:56, 25 May 2016 (UTC)
