Level 1 - Absolute Beginner
Long ago, people in England built three very big stones. The stones are called the Devil's Arrows. They stand near a town called Boroughbridge, in North Yorkshire, England.
The tallest stone is about seven meters high. That is about twenty three feet. It is the tallest stone row in Britain that still stands today.
New scientists studied the stones. They come from Curtin University in Australia and the University of York in England. They found where the stones come from.
The stones come from a place called Brimham Rocks. It is eighteen kilometers away. Each stone weighs about twenty five tons. People moved the huge stones without trucks or machines, about four thousand years ago.

Level 2 - Elementary
In North Yorkshire, England, near the small town of Boroughbridge, three enormous standing stones rise from the ground. They are known as the Devil's Arrows, and the tallest one reaches about seven meters, or twenty three feet, into the sky. It is the tallest surviving prehistoric stone row anywhere in Britain.
A team of researchers from Curtin University in Australia and the University of York in England recently studied these stones using geological analysis. Their goal was to discover exactly where the huge blocks of gritstone had originally come from.
The scientists learned that the stones were quarried at Brimham Rocks, a rugged, rocky area about eighteen kilometers, or eleven miles, west of the monument. Each stone weighs around twenty five tons, which is roughly as heavy as several elephants.
Ancient builders moved and raised these stones about four thousand years ago, during the Late Neolithic or Early Bronze Age. They had no wheels, no engines, and no modern tools. Instead, they likely used simple methods like sledges, rollers, and ropes, along with the strength of many people and animals working together.

Level 3 - Intermediate
Rising above the flat farmland near Boroughbridge in North Yorkshire, the three colossal stones known as the Devil's Arrows have puzzled visitors for centuries. The tallest of the trio stands roughly seven meters, or twenty three feet, above the surface, making it Britain's tallest surviving prehistoric stone row and a striking reminder of the ambition of ancient communities.
A new study, published in the journal Proceedings of the Royal Society A in early September 2026, brought together researchers from Curtin University in Australia and the University of York in England to investigate a long standing question: where, precisely, did these gritstone pillars originate? Through detailed geological analysis, the team traced the stones to Brimham Rocks, a distinctive upland outcrop roughly eighteen kilometers, or eleven miles, to the west.
What makes this finding significant is not merely the distance involved, but the deliberate choice it implies. Closer sources of usable stone almost certainly existed nearer to the monument's site, yet the builders instead selected material from a visually distinctive, faraway landscape. Each of these blocks weighs approximately twenty five tons, and moving them across such a distance, using only human and animal labor, sledges, rollers, and rope, would have demanded extraordinary planning and cooperation.
The stones are believed to have been quarried, transported, and erected around 2000 BC, roughly four thousand years ago, during the transition between the Late Neolithic and Early Bronze Age. Without wheels or engines of any kind, the achievement underscores a level of communal organization and engineering skill that is easy to underestimate when looking back from a modern, mechanized world. Researchers suggest that the specific origin of the stone, and the effort of the journey itself, may have carried cultural or ceremonial meaning for the people who built the monument.

Level 4 - Advanced
Amid the pastoral flatlands surrounding Boroughbridge in North Yorkshire stand three monolithic gritstone pillars, the Devil's Arrows, whose tallest member soars nearly seven meters, or twenty three feet, above the turf, a scale that renders it Britain's tallest surviving prehistoric stone row. For generations, the monument's origins have invited speculation, but a rigorous new study is finally supplying answers grounded in geology rather than legend.
Published in the journal Proceedings of the Royal Society A in early September 2026, the research, conducted jointly by teams at Curtin University in Australia and the University of York in England, applied precise geological sourcing techniques to trace the monument's raw material to Brimham Rocks, an unmistakable upland formation situated some eighteen kilometers, or eleven miles, to the west.
The significance of this discovery lies less in the distance itself than in what it reveals about intention. Suitable stone likely lay far closer at hand, yet the builders evidently bypassed those nearer sources in favor of a visually and topographically distinctive quarry. Each pillar, weighing approximately twenty five tons, would have required an extended and coordinated effort, sledges, timber rollers, ropes, and the combined muscle of people and draft animals, to traverse that terrain without benefit of the wheel or any mechanical advantage.
Archaeologists date the monument's construction to roughly 2000 BC, near the boundary between the Late Neolithic and Early Bronze Age, an era typically associated with modest technological means yet, as this evidence attests, remarkable logistical sophistication. The researchers propose that the selection of a distant, distinctive stone source, and the sheer labor of its transport, may have functioned as more than mere practicality: it possibly carried ceremonial or cultural weight, transforming the act of construction itself into a meaningful ritual of communal achievement.
