What can you tell me about Stonehenge?

It was basically a big stone calendar and place of worship. 🤷‍♀️ It was also not the only one of its kind, though most henges were wooden and it is the largest stone one found.
(However, many folk religious structures were buried to hide them, so it's possible there are larger ones still yet to be discovered.)

Bunch of rocks

The last documentary I saw used 'ground x-rays' which discovered human bones beneath or around eah of the henges themselves.

There is a BBC documentary on youtube, I believe. I think 2016 or 2018 called...possibly ' The Mystery of Stonehenge'...

Probably nothing that isn't already in your book on the subject, lol

It was a circle.
