Scientists have discovered a hidden complex of archaeological monuments at Stonehenge, challenging the modern impression that it stood in isolation.

They found the previously unknown structures when they scanned a wide area around the site, to a depth of ten feet.

They also discovered evidence of up to 60 huge pillars within the mile-wide site at nearby Durrington Walls, and a wooden burial house 3,000 years older than Stonehenge.
