The study found that Stonehenge was built from the Welsh megalithic site

Archaeologists believe the rocks at the prehistoric Stonehenge site in England may have come from another site in Wales, some 200 miles[200 km]away, which may have unraveled some of the mysteries surrounding these famous megaliths.

Their study, published in the British Archaeological Magazine Antiquity and airing a documentary on the BBC on Friday, thanks to clay sediments and coal dating, van Mann’s stone circle (in southwestern Wales), was built 400 years ago in Stonehenge.

University College London (UCL) researchers believe its builders may have moved the blue and gray stones (characteristic of Wales) from Stonehenge when their community migrated to England.

Scientists have observed that a circle from 3000 BC on the megalithic site, a UNESCO World Heritage Site, copied Van Mann’s structure, the same diameter (110 m) and the same arrangement facing the sunrise. Summer.

This discovery explains a lot about the Stonehenge site, why its monoliths were not built near their quarry, as with most sites from the same period.

With only four monoliths left, Van Mann is one of the oldest rock formations in the UK and the third largest in the country. The area around 3000 BC is a large and densely populated area, and operations appear to have abruptly ceased.

“It (the inhabitants) seems to have disappeared. Many people have emigrated and their stones (identities of their ancestors) can be taken with them, ”said UCL Professor Parker Pearson.

With about 80 stones, Stonehenge’s megalithic site must have taken stones from monuments other than Van Mann, the professor estimated: “Perhaps other (monuments) can be found in Presley. Anyone know? ”
