The researchers revealed in 2019 the stones got here from an historical quarry on the north aspect of the Preseli Hills in western Wales, which meant the 43 large bluestones had been moved a staggering distance of 150 miles.
Now, archaeologists have stated they suppose a number of the bluestones first shaped one other stone circle near the identical space because the quarries and had been dismantled and rebuilt as a part of Stonehenge on the Salisbury Plain.
The an identical 110-meter diameters of the stone circle, generally known as Waun Mawn, and the enclosing ditch of Stonehenge, recommend that at the least a part of the circle was introduced from its location in Wales to Salisbury Plain, in line with new analysis revealed within the journal Antiquity.
What’s extra, each stone circles are aligned on the midsummer solstice dawn, and one of many bluestones at Stonehenge has an uncommon cross-section that matches one of many holes left at Waun Mawn, the paper stated.
Chippings in that gap are of the identical rock sort because the Stonehenge stone, it added.
Telltale stone holes
Stonehenge is product of two varieties of stone: bigger sarsen stones and smaller bluestone monoliths.
Some 43 bluestones survive right now at Stonehenge, although many of those stay buried beneath the grass.
They had been thought to have been the primary to be erected at Stonehenge 5,000 years in the past, centuries earlier than the bigger sarsen stones had been introduced over simply 15 miles from the monument.
The Stones of Stonehenge analysis venture is led by Mike Parker Pearson, a professor at College School London.
Discovering the dismantled stone circle at Waun Mawn occurred by way of trial and error, the information assertion stated.
Solely 4 stones had been seen on the website. It was thought in 2010 that they had been a part of a stone circle, however preliminary geophysical research had been inconclusive and the staff determined to focus their energies elsewhere.
A trial excavation on the website in 2017 discovered two empty stone holes, however floor radar surveys had been nonetheless unsuccessful, leaving the staff with no selection however to do it the old style manner and dig.
Excavations in 2018 revealed empty stone holes, confirming that the 4 remaining stones had been a part of a former circle.
Courting of charcoal and sediments within the holes discovered the Waun Mawn stone circle was erected round 3400 BC, the research stated.
The paper additionally prompt that the stones might have been moved as folks migrated from that a part of Wales, with the primary folks to be buried at Stonehenge thought prone to have as soon as lived on this area.
“My guess is that Waun Mawn was not the one stone circle that contributed to Stonehenge,” stated Parker Pearson in a information assertion.
“Possibly there are extra in Preseli ready to be discovered. Who is aware of? Somebody will probably be fortunate sufficient to seek out them.”
