Isn't it strange when threads re-appear after a few years? I initially thought "who's posting under my name?".
I've read a lot about Avebury since then. It's almost unbelievable to see what a ruined monument Avebury was before the (partial) renovation. It's not hard to see how only two stones remain from the Beckhampton avenue.
Incidentally, if you look at the famous 'plan from the air' Stuckely print, (page 48 of the current Burl Avebury book, I've got a large print of this), there's shitloads of stones marked as 'a stone fallen'. Three would be under the Red Lion area! There are two under the track way marked 'to Marlborough' (Green Street?)
Anyway, what a great title for a thread, though I say so mesen'.
