The Altar Stone is one of the roughly 80-plus stones still on site in southern England .

It was long believed to originate from Wales , but a new study may have upended that theory.

Researchers studied the age and chemistry of mineral grains within fragments of the six-ton Alter Stone .

The study suggests the stone came from rocks in Scotland , at least 750 kilometers away from Stonehenge.
