a slideshow at Yahoo! that accompanies
an article about the latest theory about Stonehenge, which is that the ancient people who built Stonehenge thought the bluestones (which were lugged over 150 miles, with great effort given the technology, or lack of, then, from Wales) had some magical healing properties.
(Speaking of Stonehenge and rock groups: Stonehenge has a cameo appearance in the Beatles' movie Help!, part of which is filmed on Salisbury Plain. At one point you can see it over George's shoulder as he's singing "I Need You.")
