Prehistoric builders transported massive stones over 18 kilometers for Devil's Arrows
New research traces the source of the Devil's Arrows stones to Brimham Rocks, 18 kilometers away, not the closer Plumpton Rocks. The 25-tonne stones were moved during the Late Neolithic or Early Bronze Age, indicating remarkable planning and effort. The distant source may have held cultural or spiritual significance.
The Devil's Arrows stand near Boroughbridge, reaching heights of up to seven meters. Researchers employed a non-destructive method, using adhesive tape to extract microscopic mineral grains from the monoliths. Analyzing the age signatures of these grains allowed the team to definitively link the stones to Brimham Rocks, effectively dismissing the earlier hypothesis that they came from the closer Plumpton Rocks.
This geological matching also eliminated the possibility that glaciers carried the massive boulders to their current location. The deliberate transport of these 25-tonne blocks across 18 kilometers of rugged terrain implies a highly organized prehistoric society. The study's findings suggest that the specific landscape of Brimham Rocks held profound significance for the builders, outweighing the immense logistical challenges of moving such heavy loads.
This discovery could reshape archaeological understanding of Neolithic and Bronze Age social organization. By demonstrating that ancient communities invested immense effort to source materials from distant, specific locations, the research may prompt scholars to reconsider the spiritual and territorial motivations behind other megalithic monuments. For the general public, it could deepen appreciation for prehistoric engineering capabilities, while heritage organizations may use this new evidence to enhance interpretive narratives at sites like the Devil's Arrows, potentially boosting cultural tourism and educational engagement.
