Julian Cope presents Head Heritage

I also don't think the henge wall would be the likely intended viewing point. From a ceremonial point of view (literally) seeing it from inside the henge seems much more likely to have been considered important.

In any case, the henge wall at the relevant point is much lower than it was originally, having been demolished to allow tourist Stage coaches through (no piddling about planning visitors centres in those days, just bish, bash, done!)

The original henge wall (I think) would have been exactly on a line in space running from Silbury, the shoulder of Waden, skimming the henge wall and into the eyeball of a shortish person standing a few feet across from the obelisk. Four points in perfect three dimensional alignment. Chance or deliberate? Spoilsport Littlestone points out Waden might have been wooded, thereby making it chance at a stroke. But WAS it wooded?
