Egbert Stone. Question & Answer dated 11 Sep 2007. “Coombe Street” is not a village but a street in the village of Penselwood. I have recently photographed the nearby boundary stone at the meeting of Wiltshire, Somerset and Dorset, and can send you a .jpg if you are interested. It is in very boggy ground right beside the River Stour (which of course rises at Stourhead) with perhaps one metre of stone above ground and who knows how much below ground out of sight. It looks as though the stone is possibly of greensand, but it’s well covered by mosses or lichens. It’s on private land and not supposed to be publicly accessible (!) Is it the “Egbert Stone” though? After all this time who can tell? Graham Hoddinott
