Stonehenge’s 6-ton altar stone may have traveled from Scotland by glacier

Recent geological research provides new insights into the origin of Stonehenge’s famous six-ton Altar Stone. While historically assumed to have originated from local sources or Wales, geochemical analysis suggests the rock actually traveled from the Orcadian Basin in northeast Scotland. Researchers propose a compelling theory involving a two-stage transport process: the stone was likely transported south by natural glacial activity toward the North Sea region, now known as Dogger Bank, during the last glacial maximum. Subsequently, prehistoric human groups recovered the stone and organized a massive logistical effort to transport it hundreds of kilometers across the landscape to Salisbury Plain. This discovery challenges previous assumptions about Neolithic trade networks and suggests that the builders of Stonehenge possessed significant organizational capabilities and a long-term cultural appreciation for specific geological materials long before the final construction phases of the monument.
