"it's only medieval archaeology that's at risk."
You keep saying this.
But I keep saying - we can't know that for sure.
Those stones, they're (we presume) pretty much where they stood. So there'll be information in the original socket holes. In the layers of soil that were disturbed in prehistoric times. In the soil around the bottom of the stones. I don't know, undisturbed in the base of the stones themselves maybe. Possibly, no one right now knows.
But they might in the future. So it's best not to reerect all of them. In case. You see.
(and, btw my quotes look fine to me on TMA? Maybe you've got a different browser?)
