Is it possible that the stones in Stonehenge originated from Carnac?
Short answer: No, that is geologically and archaeologically impossible. The stones of Stonehenge do not come from Carnac (Brittany, France), but from the United Kingdom itself. Thanks to advanced chemical and mineralogical research, the exact origin of virtually all the stones at Stonehenge has been mapped out: The large Sarsen stones (the outer ring and trilithons): These gigantic silcrete/sandstone blocks originate from West Woods on the Marlborough Downs in Wiltshire, England, just about 25 kilometers (15 miles) away from Stonehenge.
