Stonehenge was a hospital!

I'm all for this theory, and what a great example of how going to the relevant locations & looking around can pay off... Stonehenge was a place of healing, a hospital of sorts

The answer had to lie in Preseli itself, in the hills of Carn Menyn and Carn Goedog where Stonehenge's dolerite and rhyolite bluestones were quarried. (They are still littered with the prehistoric quarrymen's discarded monoliths.) ...

What is most remarkable about Preseli is the plethora of springs on the hillside. Many "holy wells" have been ascribed miraculous healing powers throughout history. But Preseli's are remarkable for their number and for the dolmens, enclosures and barrows surrounding the area. More remarkable still, in front of each are bluestones, rearranged and decorated as if to create an altar and a pool. This was clearly a place of prehistoric pilgrimage, and the bluestones were thought to hold its magic.

The bluestones were used to "authenticate" Stonehenge as a healing center. This explains all the nearby burials of folk with something wrong with them...

Meanwhile, a 15th century manuscript shows Stonehenge how it looked back then (same as today, but with more stones).
