btw) There is a lot more to the subject, and Stonehenge perhaps deserves a couple of chapters on its own.
A truly remarkable piece of Engineering, not so much from a physical construction perspective but from the profound astronomical knowledge encoded within it. I struggle to reconcile that with a neolithic culture.
History, imho, is way more interesting than any fiction I have come across.
