Scientists solve the mysterious origin of the megaliths of Stonehenge



The truth is not there.

Scientists say they have finally indicated the origin of the megaliths at the 5,000-year-old Stonehenge monument.

Fifty of the 52 stone sarsens, as they are called, used in the monument were set aside about 15 miles away from the West Woods in Wiltshire, the researchers announced Wednesday after using testing. geochemical to trace their origin.

The sarsens were built at Stonehenge in 2500 BC, with the tallest reaching 30 feet high and the heaviest weighing 30 tons.

Stonehenge’s younger bluestones have a history of different origins. Those stones have already been traced back to Pembrokeshire in Wales – about 150 miles away. But the source of sarsens has so far eluded scientists.

“The sarsen stones form the iconic outer ring and seeds of Stonehenge̵

7;s central trilithon. They are huge,” said David Nash, a geomorphologist at the University of Brighton who led the study.

Researchers are now trying to understand how the sarsens were moved from Wiltshire to Stonehenge. It is believed that they were pulled on a sled-like system.

“Moving to the site is still really the subject of speculation,” Nash continued. “Because of the size of the stones, they must have either been dragged or moved on rollers to Stonehenge. We don’t know the exact route but at least we now have a starting point and endpoint.”

The discovery of Nash and his team is based on the analysis of a fragment of sarsen stone that was removed by Stonehenge in the late 1950s during a conservation effort. The piece was extracted when conservators installed metal rods to stabilize a split megalith.

That fragment was originally given as a souvenir to Robert Phillips, a man who worked for the company that carried out the stabilization effort. Phillips had carried the rock with him when he emigrated to the United States. He returned the stone to Britain for research in 2018, before leaving us earlier this year.

With authorities stopping destructive testing at the Stonehenge site, the ancient remembrance was a crucial specimen for researchers, giving them the opportunity to shape the geochemical footprint of sarsen.

“I hope what we found,” Nash said, “will let people understand more about the enormous effort involved in building Stonehenge.”
