Stonehenge, built around 5000 years ago, is one of the most famous monuments
in the world. But its origins
still remain a bit of a mystery. We do know Stonehenge is huge
outer stones came from England and the smaller inner stones from Wales. Now experts have discovered
the structure is altar stone. It came from Scotland and not from Wales
as once thought. It's a loss of Wales, no doubt. But Wales has contributed
so many rocks to this monument. I'm sure Scotland can have one. Welsh PhD student Anthony Clarke,
who made the discovery, studied the giant rock and found
it had a unique date and chemical makeup. He says it could have only come
from the far north of Scotland. So this is the altar stone the heart of
Stonehenge, now partially buried. It's one of the largest stones
here at around six tonnes. The big question is how on earth
it was transported from northeast Scotland
and why the people back then thought it was so important
to bring it all this way. I think what we've got to remember this is
these people were just like us in a way. You know, they were just as clever,
but they had different technologies. But to bring a stone of this size all the distance from what we now call
Scotland is really quite something. The new discovery is a big deal as it's changed the story of Stonehenge
and the people that built it. It's now a story of people across
Great Britain who are more connected than previously thought.
