Stonehenge has long been shrouded in mystery, with each new discovery adding another layer to its enigmatic history. Recent research led by Curtin University has unveiled a groundbreaking revelation about the origins of Stonehenge's massive six-ton Altar Stone, one of the monument’s most iconic features. Contrary to the long-held belief that this monolithic block originated from Wales, the new study pinpoints its origins to northeast Scotland, raising profound questions about the capabilities of ancient societies over 4,000 years ago. Published in the journal Nature, the study analyzed the age and chemistry of minerals from fragments of the Altar Stone, explains an Aberystwyth University press release. The findings show a remarkable similarity between the Old Red Sandstone of the Orcadian Basin in northeast Scotland and the Stonehenge Altar Stone. Anthony Clarke from the Timescales of Mineral Systems Group at Curtin University said: “Considering the technological constraints of the Neolithic, our findings raise fascinating questions about how such a massive stone was able to be transported over the vast distance implied. Given major overland barriers en route from north-east Scotland to Salisbury Plain, marine transport is one feasible option.” Read moreSection: NewsHistory & ArchaeologyEuropeAncient PlacesRead Later
