A new study published in the Journal of Quaternary Science reveals that Stonehenge's altar stone, a 4,500-year-old megalith, originated in northeast Scotland, not Wales as previously believed. Researchers from Curtin University, Sheffield Hallam University, and other institutions used geological fingerprinting to trace the stone's source. They propose that glaciers transported the stone partway to Dogger Bank, a now-submerged landmass in the North Sea, during the last ice age, after which Neolithic humans moved it the remaining hundreds of miles to Salisbury Plain. The study builds on earlier work ruling out glacial transport for other bluestones, suggesting a combination of natural and human effort.
This discovery reshapes understanding of Neolithic capabilities and cultural connections across ancient Britain. The altar stone's 435-mile journey implies sophisticated planning, coordination, and deep landscape knowledge among prehistoric peoples. It also suggests that the stone held cultural significance for the inhabitants of Doggerland before being incorporated into Stonehenge, highlighting the monument's role as a nexus of long-distance trade, belief, and communal effort. The findings challenge previous assumptions about the monument's construction and the mobility of ancient societies.
