(CNN) Five thousand years after Stonehenge was built, Archaeologists have finally determined the exact location The blue stones that are part of the majestic monument in the UK came from and how they were discovered.
In 2019, researchers revealed a The stones came from an ancient quarry on the north side of the Priscilly Hills in West Wales, which means that the 43 gigantic blue stones had been transported a staggering distance of 150 miles.
Now, archaeologists said they believe that some of the blue stones initially formed another stone circle near the same quarrying area and were dismantled and rebuilt as part of Stonehenge in the Salisbury Plain.
The identical diameters of 110 meters for the stone circle, known as the Waun Mawn, and the surrounding trench for Stonehenge indicate that at least part of the circle was brought from its position in From Wales to Salisbury Blaine, according to new research published in Antiquity.
What’s more, both chambers are lined up at sunrise in midsummer, and one of the blue stones in Stonehenge has an unusual cross-section that matches one of the remaining holes in the Waun Mawn, the newspaper reported.
She added that the fragments in that hole are of the same type of rock as Stonehenge.
Telltale stone holes
Stonehenge consists of two types of stones: larger sarsin stones and monoliths of blue stone.
Today around 43 blue stones live in Stonehenge, although many are still buried under the grass.
They were thought to have been the first to erect Stonehenge 5,000 years ago, centuries before the largest sarsinite stones were brought up only 15 miles from the memorial.
The Stones of Stonehenge research project is led by Mike Parker-Pearson, professor at University College London.
The news release said the discovery of Waun Mawn’s loose stone circuit was done through trial and error.
Only four stones appeared at the site. It was believed in 2010 that they were part of a stone circuit, but initial geophysical studies were inconclusive and the team decided to focus their energies elsewhere.
A pilot drilling operation at the site in 2017 revealed two empty stone holes, but ground-based radar surveys were unsuccessful, and the team was left with no choice but to do so the old-fashioned way and dig.
Excavations in 2018 revealed empty stone holes, confirming that the remaining four stones were part of a previous circuit.
The study said that the dating of coal and sediments in the holes found that the Waon Maun Stone Circle was established around 3400 BC.
The paper also suggested that the stones may have been moved when people migrated from this part Wales, with the first to be buried in Stonehenge, is believed to have once lived in this area.
“I suspect Waun Mawn wasn’t the only stone circle that contributed to Stonehenge,” Parker Pearson said in a press release.
“Maybe there are more in Priscilly waiting to find them. Who knows? Someone will be lucky enough to find them.”
