New research has revealed that Stonehenge's six-ton Altar Stone, traditionally believed to come from Wales, actually originates from northeast Scotland. The Altar Stone, a sandstone block at the heart of Stonehenge's iconic circle, was found to have mineral grains dating from 1,000 to 2,000 million years ago, distinctively matching the Orcadian Basin in Scotland. This discovery, dating the stone's transport to around 2600 BCE, suggests that advanced transport methods and societal organization existed in Neolithic Britain. The stone’s journey, covering over 460 miles, likely involved a marine shipping route along Britain's coast, indicating long-distance trade networks. This challenges previous understanding of the monument's construction and highlights the impressive capabilities of ancient Britons.
