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. It also suggests that Neolithic Britain was a far more connected and advanced society than earlier evidence indicated.
