The Altar Stone (Stone 80) is a recumbent megalith at the center of Stonehenge, dating to around 2600 BC [1]. A 2024 study published in Nature revealed that this six-ton sandstone block originated from the Orcadian Basin in northeast Scotland, overturning the long-held theory of a Welsh origin [2] [3].
