Stonehenge: Neolithic monument found at Durrington Walls (UK) – BBC News – 22nd June 2020
Stonehenge: Neolithic monument found near sacred site on Salisbury Plain (in Wiltshire), at Durrington Walls, just two miles away from Stonehenge.
From the University of Bradford in England:
Massive prehistoric circle near Stonehenge
‘Astonishing discovery’ offers new insights into lives of Neolithic ancestors
June 22, 2020
Summary: Archaeologists have discovered a major new prehistoric monument only a short distance away from Stonehenge. Fieldwork and analysis have revealed evidence for 20 or more massive, prehistoric shafts, measuring more than 10 metres in diameter and 5 metres deep. These shafts form a circle more than 2 kilometres in diameter and enclose an area greater than 3 square kilometres around the Durrington Walls henge, one of Britain’s largest henge monuments, and the famous, smaller prehistoric circle at Woodhenge.
What could be one of the largest prehistoric sites in the UK has been discovered near Stonehenge by a consortium of archaeologists led by the University of Bradford.
A massive 2km-wide ring of prehistoric ‘shafts’ up to 10m across and 5m deep has been discovered around the ‘super henge’ at Durrington Walls and the famous site at Woodhenge. The structures have been carbon-dated to about 2500BC.
Archaeologists believe the circle of shaft marks a boundary around the massive henge at Durrington. It is thought the features, along with an internal post line, could have guided people towards the religious sites and warned others not to cross the boundary.
Prof Vince Gaffney, 50th Anniversary Chair of the School of Archaeological and Forensic Sciences in the Faculty of Life Sciences, said it was extraordinary such a major find had been made so close to Stonehenge.
“The area around Stonehenge is amongst the most studied archaeological landscapes on earth and it is remarkable that the application of new technology can still lead to the discovery of such a massive prehistoric structure which, currently, is significantly larger than any comparative prehistoric monument that we know of in Britain, at least.”
“When these pits were first noted it was thought they might be natural features — solution hollows in the chalk. Only when the larger picture emerged, through the geophysical surveys undertaken as part of the Stonehenge Hidden Landscape Project, could we join the dots and see there was a pattern on a massive scale.”
Research on the pits at Durrington was undertaken by a consortium of archaeologists led by the University of Bradford as part of the Stonehenge Hidden Landscape Project (https://lbi-archpro.org/cs/stonehenge/), and with the Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology, the Universities of Birmingham, St Andrews, Warwick, the University of Wales Trinity Saint Davids, and the Scottish Universities Environmental Research Centre (University of Glasgow).
Researchers have identified up to 20 shafts but estimate there may have been more than 30 originally.
“The size of the shafts and circuit surrounding Durrington Walls is without precedent within the UK. It demonstrates the significance of Durrington Walls Henge, the complexity of the monumental structures within the Stonehenge landscape, and 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.”
Dr Nick Snashall, National Trust archaeologist for the Stonehenge and Avebury World Heritage Site, said: “As the place where the builders of Stonehenge lived and feasted Durrington Walls is key to unlocking the story of the wider Stonehenge landscape, and this astonishing discovery offers us new insights into the lives and beliefs of our Neolithic ancestors.
“The Hidden Landscapes team have combined cutting-edge, archaeological fieldwork with good old-fashioned detective work to reveal this extraordinary discovery and write a whole new chapter in the story of the Stonehenge landscape.”
The universities undertaking field research supporting this press release included the University of Bradford with the Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology the Universities of Birmingham, St Andrews, Trinity Saint David (University of Wales), Warwick, and the Scottish Universities Environmental Research Centre. The work was undertaken a part of the Stonehenge Hidden Landscapes Project and brought together experts in non-invasive geophysical prospection and remote sensing, and specialists in British prehistory and landscape archaeology in order to carry out research in one of the most important archaeological landscapes in Europe. The outstanding geophysical survey and visualization capabilities of the team has been made possible only because of the unique expertise and combined resources of the wider project partnership. an international collaboration of the Ludwig Boltzmann Gesellschaft (Austria), Amt der Niederösterreichischen Landesregierung (Austria), the University of Vienna (Austria), the Vienna University of Technology (Austria), ZAMG- the Central Institute for Meteorology and Geodynamics (Austria), Airborne Technologies (Austria), 7reasons (Austria), ÖAW- Austrian Academy of Sciences (Austria), ÖAI — Austrian Archaeological Institute (Austria), RGZM Mainz — Römisch‐Germanisches Zentralmuseum Mainz (Germany), the University of Birmingham in collaboration with the University of Bradford (GB), Arkeologerna of Statens Historiska Museer (Sweden), NIKU — Norwegian Institute for Cultural Heritage (Norway), and Vestfold fylkeskommune — Kulturarv (Norway).
