The Stonehenge megalithic monument, located in Salisbury, UK, has puzzled archaeologists for centuries. Its origin dates back to about 5 thousand or 4 thousand 500 years in the past and until today there was not much clarity about its origin and how it was created. Investigators have just revealed that the huge stones 9 meters high and over 24 thousand kilos in weight, called sarsens, fThey were brought in at the same time from an area known as West Woods more than 25 kilometers away.
“Our results suggest that most sarsens at Stonehenge share a common chemistry, so we are saying that they come from the same area,” explained David Nash, the study’s lead author. The findings could help archaeologists discover how the builders transported the giant stones south.
Stonehenge originally It had 80 sarsens erected in square arches, but only 52 remain. According to Nash’s team’s analysis of the elements present in the rocks, 50 of those 52 sarsen share the same chemical composition as the West Woods rocks.
Prior to this discovery, archaeologists had speculated that the sarsens came from a nearby region called the Marlborough Downs, as “there were large gray stones at Stonehenge, and the sarsens at Marlborough Downs were large and gray,” Nash said.
“Since the builders bothered to bring Welsh blue stones to Stonehenge, why would they bother to bring sarsens from the closest location?” Nash said. At least four dozen 2-5 ton blue stones came from the Preseli Hills of Wales, about 150 miles away. “The people who built Stonehenge would not have cared about the distance,” added Nash.
The other great hypothesis that arose from this discovery is that all the sarsens could have been moved at the same time. The question remains why and what Stonehenge was built for.
