Would it, I wonder, be more 'acceptable' Nigel as an 'Introduction to Avebury' from the east via the Sanctuary to recreate what we believe to be the original timber posts circles to the said Sanctuary? Archaeos have always pondered and even speculated over the first post or hut circle being roofed. That would look quite special I would have thought and although 'new' would almost certainly have had its own timbers replaced during its time. It would take the complex back to its believed beginnings and look brilliant and very educational. The further stages could be displayed on info boards but would be even better if displayed in the hut itself...all 15ft diameter of it, although the second stage being 35ft in diameter and also speculated as being roofed because of intervening 'thin' posts would be even better.
What do folk think of that as an alternative option?
