There is rather a lot to think about when you get past all the have you never heard of stuff. Hence I attempted to highlight the bank archaeology on another thread. From being one of the least talked about aspects, other than the cliche of it not being defensive, to have to think of banks as more than spoil from the ditch is an enforced leap for public thinking. And I am not just saying that because I loathe seeing those wooden staircases at Avebury (though I do, albeit something had to be done). There was a serious proposal to mount a wooden staircase on Silbury - can you imagine that?
The point that the houses are on top of the bank of the henge of course turns theories upside down, to me it points that henges are specific gathering places, whether for ceremony or to construct another monument somewhere else in the landscape. But I also think that henges must be classed using different names because they may be function in different ways - corralling animals maybe if people have to live on the banks of the henge....
