Archaeologists carrying out an excavation at Stonehenge say they have broken through to a layer that may finally explain why the site was built.
The team has reached sockets that once held bluestones - smaller stones, most now missing or uprooted, which formed the site's original structure.
The researchers believe that the bluestones could reveal that Stonehenge was once a place of healing.
There are three excellent videos at the site (well, the top and bottom ones re good; the middle, eh). I first posted about this here and while I remain skeptical of the Lourdes-ishness of the place, they seem to be really finding out a good deal. Also go here for much more. really a quite impressive job they've done.
UPDATE: But this really explains it!
