An exciting new discovery in the area around Stonehenge could be under threat from a proposed upgrade to the A303.
Archaeologists have uncovered a stone age 'eco home' - built around the base of a fallen tree and using animal hides for cover.
At 6,000 years old, the site is more than 1,000 years older than Stonehenge, but experts warn that this site and others like it could be destroyed by a planned tunnel in the area.
