Research on Stonehenge
Stonehenge has been the subject of speculation and theory since the Middle Ages. Our understanding of it is still changing as excavations and modern scientific techniques yield more information. Yet there are many questions about the monument that we have still to answer. Many of these questions are set out in the Stonehenge and Avebury World Heritage Site Research Framework, which was published in 2016.
The first known excavation at Stonehenge, in the centre of the monument, was undertaken in the 1620s by the Duke of Buckingham, prompted by a visit by King James I. The king subsequently commissioned the architect Inigo Jones to conduct a survey and study of the monument. Jones argued that Stonehenge was built by the Romans.
The antiquary John Aubrey surveyed Stonehenge in the late 17th century, and was the first to record the Aubrey Holes (hence their name). His studies of stone circles in other parts of Britain led him to conclude that they were built by the native inhabitants, rather than Romans or Danes as others had proposed. As the Druids were the only prehistoric British priests mentioned in the classical texts, he attributed Stonehenge to the Druids.
Aubrey’s idea was expanded by the 18th-century antiquary William Stukeley, who surveyed Stonehenge and was the first to record the Avenue and the nearby Cursus. Among Stukeley’s theories about Stonehenge, he too thought it was a Druid monument.
Early Excavations and Survey
In 1874 and 1877 Flinders Petrie surveyed Stonehenge in detail, and devised the numbering system for the stones that is still in use today.
Concerns about the stability of the stones (especially after one of the sarsen stones and its lintel had fallen down) led to the straightening of a large leaning trilithon in 1901. Professor William Gowland directed excavations around the base of the stone, and based on the finds, he proposed a late Neolithic or early Bronze Age date for Stonehenge.
A further programme of restoration and excavation, led by Lieutenant-Colonel William Hawley, was carried out between 1919 and 1926, when most of the south-eastern half of the monument was excavated.
Mid-20th Century Excavations
Between 1950 and 1964 Professor Richard Atkinson, Stuart Piggott and JF Stone undertook a new campaign of excavations, partly to resolve some unanswered questions left by Hawley and partly in response to a large programme of stabilisation and re-erection works at the monument. Atkinson proposed a three-stage chronology for Stonehenge. No detailed archaeological report was completed but the excavations were published in 1995.
Excavations in 1966–7 in advance of new visitor facilities led to the discovery of Mesolithic postholes, the ‘Stonehenge Archer’ was discovered in 1978, and a trench dug alongside the old A344 revealed a new stone hole, for a ‘partner’ to the Heel Stone.
In 2008, two excavations within the stone circle took place – one with the aim of investigating the early bluestone settings and another to retrieve cremation burials from Aubrey Hole 7. These targeted research excavations were both part of wider investigations into Stonehenge, its stones and its landscape.
The bluestone circuit excavations were part of the SPACES project (Strumble–Preseli Ancient Communities and Environmental Study) which has included fieldwork in the Preseli Hills and geological analysis of the bluestones. The Aubrey Hole 7 excavations were part of the much larger Stonehenge Riverside Project (2005–9) which included excavations at several monuments in the Stonehenge landscape, including the Stonehenge Cursus, Durrington Walls, West Amesbury and the Avenue.
The cremations from Aubrey Hole 7 have now been analysed, revealing that cremations of men, women and children were deposited at Stonehenge over five centuries between 3000 and 2500 BC. Analysis of the animal bones and pottery excavated at Durrington Walls during the Stonehenge Riverside Project has given new insights into the diet, cooking practices, religious beliefs and movements of the people who built Stonehenge.
Other discoveries at Stonehenge in recent years have included many more Bronze Age carvings on the stones, and new information about the way the stones were shaped and worked, through analysis of the 2011 laser scan of the monument. Parchmarks spotted in the grass during a hot spell in the summer of 2013 have led to renewed discussions about the completion of the sarsen stone circle. Excavations took place at Stonehenge in 2013 when the old A344 road bed was removed, revealing traces of the avenue ditches and a small part of the Heel Stone ditch.
Excavation in 2008 by the SPACES project led to the discovery of evidence for Roman activity at Stonehenge, in the form of a large pit, seen here in the centre of the trench.
Future Research Questions
There are many research questions about Stonehenge that we have yet to answer. Those listed here are just a selection. A set of research questions for the wider World Heritage Site is set out in the Stonehenge WHS archaeological research framework.
- Understanding previous excavations: The mid-20th-century excavations at Stonehenge, published in 1995, pre-dated the widespread use of digital software. Recent revisions to the accepted chronology and stratigraphy have highlighted the need for a digital model or 3D map of all known archaeological features and contexts found in previous investigations.
- Why was Stonehenge built here? Natural features known as periglacial stripes run parallel with the line of the Avenue, which we need to investigate further to understand whether they influenced its location. Geophysical surveys, which have discovered what may be earlier monuments in the landscape, and analysis of earthworks that may pre-date the earthwork enclosure, such as ‘North Barrow’, have the potential to shed light on why this location was chosen.
- What was the sequence of construction? The revised sequence for Stonehenge was published in 2012, and a simplified version of this schema has been adopted in the visitor centre exhibition and current guidebook. New dates from the cremations at Stonehenge have added to our understanding of the use of the monument in this first phase. Further radiocarbon dating of material from Stonehenge might add more information to the debate.
- Was the sarsen circle ever complete? The south-west side of the sarsen circle lacks several stones and has some irregular uprights. Although recent geophysical survey failed to identify stone holes in this area, parchmarks revealed in dry weather in 2013 suggest that further survey work might answer questions about the archaeology in this area.
- Who built and used Stonehenge? We now know a huge amount about the settlement at Durrington Walls two miles away, where the builders of Stonehenge may have lived. Full publication of this site, including the 2016 excavations there, will tell us much more about the people who may have built Stonehenge.
- Where were the stones brought from? Ongoing geological analysis of the bluestones and their possible sources in south-west Wales should enable us to pinpoint their origin more accurately. But questions remain about where the sarsens came from: the Stones of Stonehenge project, and future developments in geological analysis, may shed light on this.
An air of mystery and intrigue will always surround Stonehenge. Over the last ten years, however, our understanding has moved on dramatically – each new piece of evidence has brought answers and established further questions. The story of Stonehenge continues to evolve and change.
