That's a huge site - it appears to consist of at least three rings, plus there are signs of other structures surrounding it too. It'll be very interesting to see what preliminary digs and geophysics surveys discover.

Speaking of which, what do you think the purpose of Stonehenge was/is?

There is much about our history that is lost and buried, we need to keep searching our past if we are to reliably chart a way forward. Religion has definitely not helped in this regard, burying the old sites under their new sites. The churches and cathedrals I saw in South America were often built on top of the old Incan temples in a symbolic usurping of one god's power by another newer god.

Another fabulous hole in the ground .

Awesome.
