We don't have that much mystery about Stone Henge. An old physics teacher of mine was an expert on Stone Henge, back in the 80s and did a lot of original research. It's pretty clear what Stone Henge does, why it does it and how it was built. Mystery is for pop science papers.

I believe the mystery is around the lost technology to build such things.

nothing is lost - it's hard labor, barges floating stones up rivers, A-frame's to lift them...

...there have been COUNTLESS documentaries in the UK showing time and time again surprisingly small teams of people erecting megalithic monuments
