Having just been to a Swedish sale midsummer celebration in Hyde Park I guess this would be the English midsummer celebration.

It can't scale there's only one Stonehenge after all.

However we could 3D print some Stongehenge stones, they wouldn't need to be at full scale mind you perhaps 1:12 should be sufficient...

Line them up for dawn in a suitable orientation, I guess you'd need to be an astronomer.

There's a concrete analogue in Western Australia. It's a bit "enter and exit via the gift shop" but I caught glimpses from the roadside.

There's possibly 2 more. Certainly a "car henge" which may or may not be aligned to the solar cycles.
