Stonehenge has a new age — and a new purpose.
It's long been understood that the Neolithic stone circle on Salisbury Plain in southern England was an observatory tuned to the summer solstice and the positions of the stars.
But new excavations led by a pair of British archaeologists show that it was also a healing center, a sort of pagan Lourdes for chronically ill and crippled pilgrims from across western Europe.
