A new study suggests that Stonehenge's six-tonne altar stone, originating from north-east Scotland approximately 435 miles away, was transported by glacier to Doggerland, a now submerged neolithic site, during the last Ice Age. Researchers propose that prehistoric Britons subsequently moved the stone south to Salisbury Plain, possibly in response to rising sea levels as ice sheets melted. This theory implies the stone held cultural significance for Doggerland's inhabitants before its incorporation into Stonehenge, requiring multiple movements. The study, published in the Journal of Quaternary Science, highlights the complex planning and cooperation among Neolithic communities, suggesting the construction of Stonehenge may have been influenced by climate-induced migration and the use of ancient routes like the Berkshire Ridgeway.
