The researchers said that in an article published in the magazine, they solved the centuries-old mystery surrounding the origin of most of the large stones that form the outer circle of Stonehenge. Advances in science on Wednesday.
Based on geochemical data, scientists have found that 50 of the 52 large stones, the sarsen megaliths, come from West Woods in Wiltshire, England, about 15 miles from where the prehistoric monument stands.
Smaller stones near the center of the building, called the bluestones, were originally traced to Wales, almost 125 miles away.
The monument was built around 2500 BC and the question still remains as to how the stones, some of which weigh up to 30 tons, were transported.
“How they were relocated is still subject to speculation,” David Nash of the University of Brighton geomorphologist and chief researcher told Reuters.
“Due to the size of the stones, they had to be either pulled or moved on rollers to Stonehenge. We don’t know the exact route, but at least we have a starting point and an end point. “
A fragmented sample of the kernel, previously considered lost, was returned to the United Kingdom from the United States in 2018, allowing researchers to test. The second core was located in Salisbury, England in 2019 and the third core has not yet been located.
