A central stone of the famous Stonehenge monument in southwest England came from 750km away in northeast Scotland, surprised scientists said recently, solving one mystery but raising another: how did its prehistoric builders move the huge slab so far?
The Neolithic circle of giant stones has been a source of wonder and mystery for nearly 5,000 years – in the Middle Ages, the wizard Merlin of Arthurian legend was said to have stolen the monument from Ireland.
