So: this is probably my favorite megalithic site, because of the mystery
behind it and its uniqueness. Does anyone have an explanation for it?

No idea. If you find an explanation, please share it.

What is your favorite megalithic in Europe? And why? Other than
Stonehenge, that is -- that could be an easy choice already.

It's approachable, and doesn't feel at all touristy.
