On my long-running search for remnants of an avenue across the Medway, I came across a smallish sarsen buried deep in a pavement outside the Duke of Wellington in Ryarsh, with maybe a 2' circle still showing, 6" above the tarmac [sorry to swear]. It is on the inside of a bend, and could easily have been placed to ensure the corner of the pub doesn't get a swipe by a passing car, though it is a little low down for that. The locals have no idea, the pub owners haven't been around for long enough, and the local council are pretty uncooperative/uninterested. My Mother recalls it being there at least 25 years ago, but there was no kerb/pavement then, so it would have stood a lot more proud of the road surface.
The question is, is it worth recording?
Also, what should I do in respect of stones marked on old maps ? Are they generally accurate ? Does anyone have any experience of locating holes etc ?
