The six-tonne Altar Stone at the heart of Stonehenge came from the far north of Scotland rather than south-west Wales as previously thought, new analysis has found.

It means that the stone was brought about 700km (434 miles), from Scotland, to the ancient monument, near Salisbury in south-west England.

The discovery shows the construction of Stonehenge was a far greater collaborative effort than scientists realised.

That’s all. No need to watch the video.
