Rock Art in walls

considering the amount that's probably been quarried away, you might not be far wrong. It just won't be facing outwards....
That means there are six times as many marked stones in use as building material as we can see !!

It's not as simple as that - because of the bedding planes - somewhere between four and six, perhaps. And then there's the wall stones that retain a bank and those carved fragments that have been pointed or rendered.

might be higher than that, as if you were a stonemason wanting to make a good job, you wouldn't want those silly squiggly bits showing...

(I used to like to imagine I had some RA in my old house in Wooler - not impossible)
