Simon Jenkins is approachable - and he's got it right about some kind of curse on ths stones - I wonder how http://www.maeshowe.co.uk/main.html is doing ? I think they've a bug rather than a jinx (or maybe it's gremlins). I fancy I spied a face in the shadows of a sunset early last week - luckily caught on a screen capture.
Stonehenge is missing many stones for a restoration, but there is a good source on Timber Circles and Stonehenge that shows it wasn't a one-off but, rather, close to the tradition of log circles ! (It was inspiring to see all the tribes camped in whatisnow Festival Field, incidentally).
