Stonehenge may have been built as an enormous old amplifier, with new research suggesting our Stone Age descendants might have hauled the rocks hundreds of miles simply because they make pleasant sounds when hit with massive hammers.
A team of archaeologists from universities in Bournemouth and Bristol were granted permission by English Heritage to whack the henge, claiming the stones reverberated differently from each other and gave off subtly different sounds. This may explain why the rocks were taken 200 miles from South Wales to Salisbury Plain -- they were the world's first Walkman.
Although some of the natural sound has been muffed by the good old 1950s concrete that was used to stabilise some of the massive rocks, researchers claim the Bluestones still make subtle wooden or metallic sounds when struck, which may mean the henge was used as a primitive long-distance communication system or in a similar way to the more modern church bell.
