I'm not sure how they're planning to prove it was built for healing purposes, but if they can turn up any in situ organic material from a bluestone socket that'll be good.
There's a forlorn-looking exhibition tent in the overflow carpark at Stonehenge with a live CCTV feed from the dig, a looping trailer for TimeWatch, some touristy knicknacks and a series of large poster-like pics on the wall.
The pic of the Preseli quarry where the bluestones came from has been rather enthusiastically colour-balanced so there's absolutely no doubt that they're BLUEstones :-)
