Discovery of a ring of large shafts close to Stonehenge

StonehengeArchaeologists believe the find marks “a new chapter” in Stonehenge’s story

A ring of large shafts discovered near Stonehenge form the largest prehistoric monument ever discovered in Britain, archaeologists believe.

Tests carried out on the pits suggest they were excavated by Neolithic people more than 4,500 years ago.

Experts believe the 20 or more shafts may have served as a boundary to a sacred area connected to the henge.

“The size of the shafts and circuit is without precedent in the UK,” said Prof Vince Gaffney, a lead researcher.

The 1.2 mile-wide (2km) circle of large shafts measuring more than 10m (30ft) in diameter and 5m (15ft) in depth are significantly larger than any comparable prehistoric monument in Britain.

A team of academics from the universities of St Andrews, Birmingham, Warwick, Bradford, Glasgow and the University of Wales worked on the project.

The pits surround the ancient settlement of Durrington Walls, two miles (3km) from Stonehenge, and were discovered using remote sensing technology and sampling.

Prof Gaffney, of the University of Bradford, said the discovery demonstrated “the capacity and desire of Neolithic communities to record their cosmological belief systems in ways, and at a scale, that we had never previously anticipated”.

“The area around Stonehenge is among the most studied archaeological landscapes on earth,” he added.

“It is remarkable that the application of new technology can still lead to the discovery of such a massive prehistoric structure.

“When these pits were first noted, it was thought they might be natural features. Only through geophysical surveys, could we join the dots and see there was a pattern on a massive scale.”

Prof Gaffney said a “proper excavation” was required to determine the exact nature of the pits but that the team believed they acted as a boundary, perhaps marking out Durrington Walls as a special place, or emphasising the difference between the Durrington and Stonehenge areas.

He said it was difficult to speculate how long they would have taken to create, but using manual stone tools, there would have been “considerable organisation of labor to produce pits on this scale”.

“The pits are massive by any estimate. As far as we can tell they are nearly vertical sided; that is we can’t see any narrowing that might imply some sort of shaft. Some of the silts suggest relatively slow filling of the pits. In other words they were cut and left open,” added Prof Gaffney.

Dr Richard Bates, from St Andrews’ School of Earth and Environmental Sciences, said it had given an insight to “an even more complex society than we could ever imagine”.

His colleague Tim Kinnaird said sediments from the shafts had allowed archaeologists to “write detailed narratives of the Stonehenge landscape for the last 4,000 years”.
