James Sturcke and Maev Kennedy report in The Guardian:
Archaeologists have discovered evidence of what they believe was a second Stonehenge located a little more than a mile away from the world-famous prehistoric monument.
The new find on the west bank of the river Avon has been called “Bluestonehenge”, after the colour of the 25 Welsh stones of which it was once made up.
Excavations at the site have suggested there was once a stone circle 10 metres in diameter and surrounded by a henge – a ditch with an external bank, according to the project director, Professor Mike Parker Pearson, of the University of Sheffield.
The stones at the site were removed thousands of years ago but the sizes of the holes in which they stood indicate that this was a circle of bluestones, brought from the Preseli mountains of Wales, 150 miles away.
The standing stones marked the end of the avenue that leads from the river Avon to Stonehenge, a 1¾-mile long processional route constructed at the end of the Stone Age.
