Stonehenge

Stonehenge is a prehistoric monument on Salisbury Plain in Wiltshire, England, west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around high, wide, and weighing around 25 tons, topped by connecting horizontal lintel stones. Inside is a ring of smaller bluestones. Inside these are free-standing trilithons, two bulkier vertical sarsens joined by one lintel. The whole monument, now ruinous, is aligned towards the sunrise on the summer solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred ''tumuli'' (burial mounds).

Archaeologists believe that Stonehenge was constructed from around 3000 BC to 2000 BC. The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. Radiocarbon dating suggests that the first bluestones were raised between 2400 and 2200 BC, although they may have been at the site as early as 3000 BC.

One of the most famous landmarks in the United Kingdom, Stonehenge is regarded as a British cultural icon. It has been a legally protected scheduled monument since 1882, when legislation to protect historic monuments was first successfully introduced in Britain. The site and its surroundings were added to UNESCO's list of World Heritage Sites in 1986. Stonehenge is owned by the Crown and managed by English Heritage; the surrounding land is owned by the National Trust.

Stonehenge could have been a burial ground from its earliest beginnings. Deposits containing human bone date from as early as 3000 BC, when the ditch and bank were first dug, and continued for at least another 500 years.

Etymology

The ''Oxford English Dictionary'' cites Ælfric's tenth-century glossary, in which ''henge-cliff'' is given the meaning "precipice", or stone; thus, the ''stanenges'' or ''Stanheng'' "not far from Salisbury" recorded by eleventh-century writers are "stones supported in the air". In 1740, William Stukeley notes: "Pendulous rocks are now called henges in Yorkshire ... I doubt not, Stonehenge in Saxon signifies the hanging stones." Christopher Chippindale's ''Stonehenge Complete'' gives the derivation of the name ''Stonehenge'' as coming from the Old English words ''stān'' meaning "stone", and either ''hencg'' meaning " hinge" (because the stone lintels hinge on the upright stones) or ''hen(c)en'' meaning " to hang" or "gallows" or "instrument of torture" (though elsewhere in his book, Chippindale cites the "suspended stones" etymology).

The "henge" portion has given its name to a class of monuments known as henges. Archaeologists define henges as earthworks consisting of a circular banked enclosure with an internal ditch. As often happens in archaeological terminology, this is a holdover from antiquarian use.

Despite being contemporary with true Neolithic henges and stone circles, Stonehenge is in many ways atypical – for example, at more than tall, its extant trilithons' lintels, held in place with mortise and tenon joints, make it unique.

Early history

Mike Parker Pearson, leader of the Stonehenge Riverside Project based around Durrington Walls, noted that Stonehenge appears to have been associated with burial from the earliest period of its existence:

Stonehenge evolved in several construction phases spanning at least 1500 years. There is evidence of large-scale construction on and around the monument that perhaps extends the landscape's time frame to 6500 years. Dating and understanding the various phases of activity are complicated by disturbance of the natural chalk by periglacial effects and animal burrowing, poor quality early excavation records, and a lack of accurate, scientifically verified dates. The modern phasing most generally agreed to by archaeologists is detailed below. Features mentioned in the text are numbered and shown on the plan, right.

Before the monument (from 8000 BC)

Archaeologists have found four, or possibly five, large Mesolithic postholes (one may have been a natural tree throw), which date to around 8000 BC, beneath the nearby old tourist car-park in use until 2013. These held pine posts around in diameter, which were erected and eventually rotted ''in situ''. Three of the posts (and possibly four) were in an east–west alignment which may have had ritual significance. Another Mesolithic astronomical site in Britain is the Warren Field site in Aberdeenshire, which is considered the world's oldest lunar calendar, corrected yearly by observing the midwinter solstice. Similar but later sites have been found in Scandinavia. A settlement that may have been contemporaneous with the posts has been found at Blick Mead, a reliable year-round spring from Stonehenge.

Salisbury Plain was then still wooded, but 4,000 years later, during the earlier Neolithic, people built a causewayed enclosure at Robin Hood's Ball, and long barrow tombs in the surrounding landscape. In approximately 3500 BC, a Stonehenge Cursus was built north of the site as the first farmers began to clear the trees and develop the area. Other previously overlooked stone or wooden structures and burial mounds may date as far back as 4000 BC. Charcoal from the ‘Blick Mead’ camp from Stonehenge (near the Vespasian's Camp site) has been dated to 4000 BC. The University of Buckingham's Humanities Research Institute believes that the community who built Stonehenge lived here over a period of several millennia, making it potentially "one of the pivotal places in the history of the Stonehenge landscape."

Stonehenge 1 (c. 3100 BC)

The first monument consisted of a circular bank and ditch enclosure made of Late Cretaceous (Santonian Age) Seaford chalk, measuring about in diameter, with a large entrance to the north east and a smaller one to the south. It stood in open grassland on a slightly sloping spot. The builders placed the bones of deer and oxen in the bottom of the ditch, as well as some worked flint tools. The bones were considerably older than the antler picks used to dig the ditch, and the people who buried them had looked after them for some time prior to burial. The ditch was continuous but had been dug in sections, like the ditches of the earlier causewayed enclosures in the area. The chalk dug from the ditch was piled up to form the bank. This first stage is dated to around 3100 BC, after which the ditch began to silt up naturally. Within the outer edge of the enclosed area is a circle of 56 pits, each about in diameter, known as the Aubrey holes after John Aubrey, the seventeenth-century antiquarian who was thought to have first identified them. These pits and the bank and ditch together are known as the Palisade or Gate Ditch. The pits may have contained standing timbers creating a timber circle, although there is no excavated evidence of them. A recent excavation has suggested that the Aubrey Holes may have originally been used to erect a bluestone circle. If this were the case, it would advance the earliest known stone structure at the monument by some 500 years.

In 2013 a team of archaeologists, led by Mike Parker Pearson, excavated more than 50,000 cremated bone fragments, from 63 individuals, buried at Stonehenge. These remains had originally been buried individually in the Aubrey holes, exhumed during a previous excavation conducted by William Hawley in 1920, been considered unimportant by him, and subsequently re-interred together in one hole, Aubrey Hole 7, in 1935. Physical and chemical analysis of the remains has shown that the cremated were almost equally men and women, and included some children. As there was evidence of the underlying chalk beneath the graves being crushed by substantial weight, the team concluded that the first bluestones brought from Wales were probably used as grave markers. Radiocarbon dating of the remains has put the date of the site 500 years earlier than previously estimated, to around 3000 BC. A 2018 study of the strontium content of the bones found that many of the individuals buried there around the time of construction had probably come from near the source of the bluestone in Wales and had not extensively lived in the area of Stonehenge before death.

Between 2017 and 2021, studies by Professor Pearson (UCL) and his team suggested that the bluestones used in Stonehenge had been moved there following dismantling of a stone circle of identical size to the first known Stonehenge circle (110m) at the Welsh site of Waun Mawn in the Preseli Hills. It had contained bluestones, one of which showed evidence of having been reused in Stonehenge. The stone was identified by its unusual pentagonal shape and by luminescence soil dating from the filled-in sockets which showed the circle had been erected around 3400-3200 BC, and dismantled around 300–400 years later, consistent with the dates attributed to the creation of Stonehenge. The cessation of human activity in that area at the same time suggested migration as a reason, but it is believed that other stones may have come from other sources.

Stonehenge 2 (c. 2900 BC)

The second phase of construction occurred approximately between 2900 and 2600 BC. The number of postholes dating to the early third millennium BC suggests that some form of timber structure was built within the enclosure during this period. Further standing timbers were placed at the northeast entrance, and a parallel alignment of posts ran inwards from the southern entrance. The postholes are smaller than the Aubrey Holes, being only around in diameter, and are much less regularly spaced. The bank was purposely reduced in height and the ditch continued to silt up. At least twenty-five of the Aubrey Holes are known to have contained later, intrusive, cremation burials dating to the two centuries after the monument's inception. It seems that whatever the holes' initial function, it changed to become a funerary one during Phase two. Thirty further cremations were placed in the enclosure's ditch and at other points within the monument, mostly in the eastern half. Stonehenge is therefore interpreted as functioning as an enclosed cremation cemetery at this time, the earliest known cremation cemetery in the British Isles. Fragments of unburnt human bone have also been found in the ditch-fill. Dating evidence is provided by the late Neolithic grooved ware pottery that has been found in connection with the features from this phase.

Stonehenge 3 I (c. 2600 BC)

Archaeological excavation has indicated that around 2600 BC, the builders abandoned timber in favour of stone and dug two concentric arrays of holes (the Q and R Holes) in the centre of the site. These stone sockets are only partly known (hence on present evidence are sometimes described as forming 'crescents'); however, they could be the remains of a double ring. Again, there is little firm dating evidence for this phase. The holes held up to 80 standing stones (shown blue on the plan), only 43 of which can be traced today. It is generally accepted that the bluestones (some of which are made of dolerite, an igneous rock), were transported by the builders from the Preseli Hills, away in modern-day Pembrokeshire in Wales. Another theory is that they were brought much nearer to the site as glacial erratics by the Irish Sea Glacier although there is no evidence of glacial deposition within southern central England. A 2019 publication announced that evidence of Megalithic quarrying had been found at quarries in Wales identified as a source of Stonehenge's bluestone, indicating that the bluestone was quarried by human agency and not transported by glacial action.

The long-distance human transport theory was bolstered in 2011 by the discovery of a megalithic bluestone quarry at Craig Rhos-y-felin, near Crymych in Pembrokeshire, which is the most likely place for some of the stones to have been obtained. Other standing stones may well have been small sarsens (sandstone), used later as lintels. The stones, which weighed about two tons, could have been moved by lifting and carrying them on rows of poles and rectangular frameworks of poles, as recorded in China, Japan and India. It is not known whether the stones were taken directly from their quarries to Salisbury Plain or were the result of the removal of a venerated stone circle from Preseli to Salisbury Plain to "merge two sacred centres into one, to unify two politically separate regions, or to legitimise the ancestral identity of migrants moving from one region to another". Evidence of a 110-m stone circle at Waun Mawn near Preseli, which could have contained some or all of the stones in Stonehenge, has been found, including a hole from a rock that matches the unusual cross-section of a Stonehenge bluestone "like a key in a lock". Each monolith measures around in height, between wide and around thick. What was to become known as the Altar Stone is almost certainly derived from the Senni Beds, perhaps from east of the Preseli Hills in the Brecon Beacons.

The north-eastern entrance was widened at this time, with the result that it precisely matched the direction of the midsummer sunrise and midwinter sunset of the period. This phase of the monument was abandoned unfinished, however; the small standing stones were apparently removed and the Q and R holes purposefully backfilled.

The Heel Stone, a Tertiary sandstone, may also have been erected outside the north-eastern entrance during this period. It cannot be accurately dated and may have been installed at any time during phase 3. At first, it was accompanied by a second stone, which is no longer visible. Two, or possibly three, large portal stones were set up just inside the north-eastern entrance, of which only one, the fallen Slaughter Stone, long, now remains. Other features, loosely dated to phase 3, include the four Station Stones, two of which stood atop mounds. The mounds are known as " barrows" although they do not contain burials. Stonehenge Avenue, a parallel pair of ditches and banks leading to the River Avon, was also added.

Stonehenge 3 II (2600 BC to 2400 BC)

During the next major phase of activity, 30 enormous Oligocene–Miocene sarsen stones (shown grey on the plan) were brought to the site. They came from a quarry around north of Stonehenge, in West Woods, Wiltshire. The stones were dressed and fashioned with mortise and tenon joints before 30 sarsens were erected as a diameter circle of standing stones, with a ring of 30 lintel stones resting on top. The lintels were fitted to one another using tongue and groove joints – a woodworking method, again. Each standing stone was around high, wide and weighed around 25 tons. Each had clearly been worked with the final visual effect in mind: The orthostats widen slightly towards the top in order that their perspective remains constant when viewed from the ground, while the lintel stones curve slightly to continue the circular appearance of the earlier monument.

The inward-facing surfaces of the stones are smoother and more finely worked than the outer surfaces. The average thickness of the stones is and the average distance between them is . A total of 75 stones would have been needed to complete the circle (60 stones) and the trilithon horseshoe (15 stones). It was thought the ring might have been left incomplete, but an exceptionally dry summer in 2013 revealed patches of parched grass which may correspond to the location of missing sarsens. The lintel stones are each around long, wide and thick. The tops of the lintels are above the ground.

Within this circle stood five trilithons of dressed sarsen stone arranged in a horseshoe shape across, with its open end facing northeast. These huge stones, ten uprights and five lintels, weigh up to 50 tons each. They were linked using complex jointing. They are arranged symmetrically. The smallest pair of trilithons were around tall, the next pair a little higher, and the largest, single trilithon in the south-west corner would have been tall. Only one upright from the Great Trilithon still stands, of which is visible and a further is below ground. The images of a 'dagger' and 14 'axeheads' have been carved on one of the sarsens, known as stone 53; further carvings of axeheads have been seen on the outer faces of stones 3, 4, and 5. The carvings are difficult to date but are morphologically similar to late Bronze Age weapons. Early 21st century laser scanning of the carvings supports this interpretation. The pair of trilithons in the north east are smallest, measuring around in height; the largest, which is in the south-west of the horseshoe, is almost tall.

This ambitious phase has been radiocarbon dated to between 2600 and 2400 BC, slightly earlier than the Stonehenge Archer, discovered in the outer ditch of the monument in 1978, and the two sets of burials, known as the Amesbury Archer and the Boscombe Bowmen, discovered to the west. Analysis of animal teeth found away at Durrington Walls, thought by Parker Pearson to be the 'builders camp', suggests that, during some period between 2600 and 2400 BC, as many as 4,000 people gathered at the site for the mid-winter and mid-summer festivals; the evidence showed that the animals had been slaughtered around nine months or 15 months after their spring birth. Strontium isotope analysis of the animal teeth showed that some had been brought from as far afield as the Scottish Highlands for the celebrations.

At about the same time, a large timber circle and a second avenue were constructed at Durrington Walls overlooking the River Avon. The timber circle was orientated towards the rising Sun on the midwinter solstice, opposing the solar alignments at Stonehenge. The avenue was aligned with the setting Sun on the summer solstice and led from the river to the timber circle. Evidence of huge fires on the banks of the Avon between the two avenues also suggests that both circles were linked. They were perhaps used as a procession route on the longest and shortest days of the year. Parker Pearson speculates that the wooden circle at Durrington Walls was the centre of a 'land of the living', whilst the stone circle represented a 'land of the dead', with the Avon serving as a journey between the two.

Stonehenge 3 III (2400 BC to 2280 BC)

Later in the Bronze Age, although the exact details of activities during this period are still unclear, the bluestones appear to have been re-erected. They were placed within the outer sarsen circle and may have been trimmed in some way. Like the sarsens, a few have timber-working style cuts in them suggesting that, during this phase, they may have been linked with lintels and were part of a larger structure.

Stonehenge 3 IV (2280 BC to 1930 BC)

This phase saw further rearrangement of the bluestones. They were arranged in a circle between the two rings of sarsens and in an oval at the centre of the inner ring. Some archaeologists argue that some of these bluestones were from a second group brought from Wales. All the stones formed well-spaced uprights without any of the linking lintels inferred in Stonehenge 3 III. The Altar Stone may have been moved within the oval at this time and re-erected vertically. Although this would seem the most impressive phase of work, Stonehenge 3 IV was rather shabbily built compared to its immediate predecessors, as the newly re-installed bluestones were not well-founded and began to fall over. However, only minor changes were made after this phase.

Stonehenge 3 V (1930 BC to 1600 BC)

Soon afterwards, the northeastern section of the Phase 3 IV bluestone circle was removed, creating a horseshoe-shaped setting (the Bluestone Horseshoe) which mirrored the shape of the central sarsen Trilithons. This phase is contemporary with the Seahenge site in Norfolk.

After the monument (1600 BC on)

The Y and Z Holes are the last known construction at Stonehenge, built about 1600 BC, and the last usage of it was probably during the Iron Age. Roman coins and medieval artefacts have all been found in or around the monument but it is unknown if the monument was in continuous use throughout British prehistory and beyond, or exactly how it would have been used. Notable is the massive Iron Age hillfort known as Vespasian's Camp (despite its name, not a Roman site) built alongside the Avenue near the Avon. A decapitated seventh-century Saxon man was excavated from Stonehenge in 1923. The site was known to scholars during the Middle Ages and since then it has been studied and adopted by numerous groups.

Function and construction

Stonehenge was produced by a culture that left no written records. Many aspects of Stonehenge, such as how it was built and for what purposes it was used, remain subject to debate. A number of myths surround the stones. The site, specifically the great trilithon, the encompassing horseshoe arrangement of the five central trilithons, the heel stone, and the embanked avenue, are aligned to the sunset of the winter solstice and the opposing sunrise of the summer solstice. A natural landform at the monument's location followed this line, and may have inspired its construction. The excavated remains of culled animal bones suggest that people may have gathered at the site for the winter rather than the summer. Further astronomical associations, and the precise astronomical significance of the site for its people, are a matter of speculation and debate.

There is little or no direct evidence revealing the construction techniques used by the Stonehenge builders. Over the years, various authors have suggested that supernatural or anachronistic methods were used, usually asserting that the stones were impossible to move otherwise due to their massive size. However, conventional techniques, using Neolithic technology as basic as shear legs, have been demonstrably effective at moving and placing stones of a similar size. The most common theory of how prehistoric people moved megaliths has them creating a track of logs which the large stones were rolled along. Another megalith transport theory involves the use of a type of sleigh running on a track greased with animal fat. Such an experiment with a sleigh carrying a 40-ton slab of stone was successfully conducted near Stonehenge in 1995. A team of more than 100 workers managed to push and pull the slab along the journey from the Marlborough Downs.

Proposed functions for the site include usage as an astronomical observatory or as a religious site. In the 1960s Gerald Hawkins described in detail how the site was apparently set out to observe the sun and moon over a recurring 56-year cycle. More recently two major new theories have been proposed. Geoffrey Wainwright, president of the Society of Antiquaries of London, and Timothy Darvill, of Bournemouth University, have suggested that Stonehenge was a place of healing—the primeval equivalent of Lourdes. They argue that this accounts for the high number of burials in the area and for the evidence of trauma deformity in some of the graves. However, they do concede that the site was probably multifunctional and used for ancestor worship as well. Isotope analysis indicates that some of the buried individuals were from other regions. A teenage boy buried approximately 1550 BC was raised near the Mediterranean Sea; a metal worker from 2300 BC dubbed the "Amesbury Archer" grew up near the Alpine foothills of Germany; and the "Boscombe Bowmen" probably arrived from Wales or Brittany, France.

On the other hand, Mike Parker Pearson of Sheffield University has suggested that Stonehenge was part of a ritual landscape and was joined to Durrington Walls by their corresponding avenues and the River Avon. He suggests that the area around Durrington Walls Henge was a place of the living, whilst Stonehenge was a domain of the dead. A journey along the Avon to reach Stonehenge was part of a ritual passage from life to death, to celebrate past ancestors and the recently deceased. Both explanations were first mooted in the twelfth century by Geoffrey of Monmouth, who extolled the curative properties of the stones and was also the first to advance the idea that Stonehenge was constructed as a funerary monument. Whatever religious, mystical or spiritual elements were central to Stonehenge, its design includes a celestial observatory function, which might have allowed prediction of eclipse, solstice, equinox and other celestial events important to a contemporary religion.

There are other hypotheses and theories. According to a team of British researchers led by Mike Parker Pearson of the University of Sheffield, Stonehenge may have been built as a symbol of "peace and unity", indicated in part by the fact that at the time of its construction, Britain's Neolithic people were experiencing a period of cultural unification.

Stonehenge megaliths include smaller bluestones and larger sarsens (a term for silicified sandstone boulders found in the chalk downs of southern England). The bluestones are composed of dolerite, tuff, rhyolite, or sandstone. The igneous bluestones appear to have originated in the Preseli hills of southwestern Wales about from the monument. The sandstone Altar Stone may have originated in east Wales. Recent analysis has indicated the sarsens originated from West Woods, about from the monument.

Researchers from the Royal College of Art in London have discovered that the monument's igneous bluestones possess "unusual acoustic properties" – when struck they respond with a "loud clanging noise". Rocks with such acoustic properties are frequent in the Carn Melyn ridge of Presili; the Presili village of Maenclochog (Welsh for bell or ringing stones), used local bluestones as church bells until the 18th century. According to the team, these acoustic properties could explain why certain bluestones were hauled such a long distance, a major technical accomplishment at the time. In certain ancient cultures, rocks that ring out, known as lithophonic rocks, were believed to contain mystic or healing powers, and Stonehenge has a history of association with rituals. The presence of these "ringing rocks" seems to support the hypothesis that Stonehenge was a "place for healing" put forward by Darvill, who consulted with the researchers.

DNA studies clarify the historical context

Researchers studying DNA extracted from Neolithic human remains across Britain determined that the ancestors of the people who built Stonehenge were early European farmers who came from the Eastern Mediterranean, travelling west from there, as well as Western hunter-gatherers from western Europe. DNA studies indicate that they had a predominantly Aegean ancestry, although their agricultural techniques seem to have come originally from Anatolia. These Aegean farmers then moved to Iberia before heading north, reaching Britain in about 4,000 BC.Paul Rincon
Stonehenge: DNA reveals origin of builders.
BBC News website, 16 April 2019 Neolithic individuals in the British Isles were close to Iberian and Central European Early and Middle Neolithic populations, modelled as having about 75% ancestry from Aegean farmers with the rest coming from Western Hunter-Gatherers in continental Europe. They subsequently replaced most of the hunter-gatherer population in the British Isles without mixing much with them. At that time, Britain was inhabited by groups of hunter-gatherers who were the first inhabitants of the island after the last Ice Age ended about 11,700 years ago. Despite their mostly Aegean ancestry, the paternal (Y-DNA) lineages of Neolithic farmers in Britain were almost exclusively of Western Hunter-Gatherer origin. This was also the case among other megalithic-building populations in northwest Europe,

meaning that these populations were descended from a mixture of hunter-gatherer males and farmer females.
This mixture appears to have happened primarily on the continent before the Neolithic farmers migrated to Britain. The dominance of Western Hunter-Gatherer male lineages in Britain and northwest Europe is also reflected in a general 'resurgence' of hunter-gatherer ancestry, predominantly from males, across western and central Europe in the Middle Neolithic.

The Bell Beaker people arrived later, around 2,500 BC, migrating from mainland Europe. The earliest British beakers, most likely speakers of Indo-European languages whose ancestors migrated from the Pontic–Caspian steppe, were similar to those from the Rhine. There was again a large population replacement in Britain. More than 90% of Britain's Neolithic gene pool was replaced with the arrival of the Bell Beaker people, who had approximately 50% WSH ancestry. The Bell Beakers also left their impact on Stonehenge construction. They are also associated with the Wessex culture''.

Stone 22 fell during a fierce storm on 31 December 1900.

1901–2000

William Gowland oversaw the first major restoration of the monument in 1901, which involved the straightening and concrete setting of sarsen stone number 56 which was in danger of falling. In straightening the stone he moved it about half a metre from its original position. Gowland also took the opportunity to further excavate the monument in what was the most scientific dig to date, revealing more about the erection of the stones than the previous 100 years of work had done. During the 1920 restoration William Hawley, who had excavated nearby Old Sarum, excavated the base of six stones and the outer ditch. He also located a bottle of port in the Slaughter Stone socket left by Cunnington, helped to rediscover Aubrey's pits inside the bank and located the concentric circular holes outside the Sarsen Circle called the Y and Z Holes.

Richard Atkinson, Stuart Piggott and John F. S. Stone re-excavated much of Hawley's work in the 1940s and 1950s, and discovered the carved axes and daggers on the Sarsen Stones. Atkinson's work was instrumental in furthering the understanding of the three major phases of the monument's construction.

In 1958 the stones were restored again, when three of the standing sarsens were re-erected and set in concrete bases. The last restoration was carried out in 1963 after stone 23 of the Sarsen Circle fell over. It was again re-erected, and the opportunity was taken to concrete three more stones. Later archaeologists, including Christopher Chippindale of the Museum of Archaeology and Anthropology, University of Cambridge and Brian Edwards of the University of the West of England, campaigned to give the public more knowledge of the various restorations and in 2004 English Heritage included pictures of the work in progress in its book ''Stonehenge: A History in Photographs''.

In 1966 and 1967, in advance of a new car park being built at the site, the area of land immediately northwest of the stones was excavated by Faith and Lance Vatcher. They discovered the Mesolithic postholes dating from between 7000 and 8000 BC, as well as a length of a palisade ditch – a V-cut ditch into which timber posts had been inserted that remained there until they rotted away. Subsequent aerial archaeology suggests that this ditch runs from the west to the north of Stonehenge, near the avenue.

Excavations were once again carried out in 1978 by Atkinson and John Evans, during which they discovered the remains of the Stonehenge Archer in the outer ditch, and in 1979 rescue archaeology was needed alongside the Heel Stone after a cable-laying ditch was mistakenly dug on the roadside, revealing a new stone hole next to the Heel Stone.

In the early 1980s Julian C. Richards led the Stonehenge Environs Project, a detailed study of the surrounding landscape. The project was able to successfully date such features as the Lesser Cursus, Coneybury Henge and several other smaller features.

In 1993 the way that Stonehenge was presented to the public was called 'a national disgrace' by the House of Commons Public Accounts Committee. Part of English Heritage's response to this criticism was to commission research to collate and bring together all the archaeological work conducted at the monument up to this date. This two-year research project resulted in the publication in 1995 of the monograph '' Stonehenge in its landscape'', which was the first publication presenting the complex stratigraphy and the finds recovered from the site. It presented a rephasing of the monument.

21st century

More recent excavations include a series of digs held between 2003 and 2008 known as the Stonehenge Riverside Project, led by Mike Parker Pearson. This project mainly investigated other monuments in the landscape and their relationship to the stones — notably, Durrington Walls, where another "Avenue" leading to the River Avon was discovered. The point where the Stonehenge Avenue meets the river was also excavated and revealed a previously unknown circular area which probably housed four further stones, most likely as a marker for the starting point of the avenue.

In April 2008, Tim Darvill of the University of Bournemouth and Geoff Wainwright of the Society of Antiquaries began another dig inside the stone circle to retrieve datable fragments of the original bluestone pillars. They were able to date the erection of some bluestones to 2300 BC, although this may not reflect the earliest erection of stones at Stonehenge. They also discovered organic material from 7000 BC, which, along with the Mesolithic postholes, adds support for the site having been in use at least 4,000 years before Stonehenge was started. In August and September 2008, as part of the Riverside Project, Julian C. Richards and Mike Pitts excavated Aubrey Hole 7, removing the cremated remains from several Aubrey Holes that had been excavated by Hawley in the 1920s, and re-interred in 1935. A licence for the removal of human remains at Stonehenge had been granted by the Ministry of Justice in May 2008, in accordance with the ''Statement on burial law and archaeology'' issued in May 2008. One of the conditions of the licence was that the remains should be reinterred within two years and that in the intervening period they should be kept safely, privately and decently.

A new landscape investigation was conducted in April 2009. A shallow mound, rising to about was identified between stones 54 (inner circle) and 10 (outer circle), clearly separated from the natural slope. It has not been dated but speculation that it represents careless backfilling following earlier excavations seems disproved by its representation in eighteenth- and nineteenth-century illustrations. There is some evidence that, as an uncommon geological feature, it could have been deliberately incorporated into the monument at the outset. A circular, shallow bank, little more than high, was found between the Y and Z hole circles, with a further bank lying inside the "Z" circle. These are interpreted as the spread of spoil from the original Y and Z holes, or more speculatively as hedge banks from vegetation deliberately planted to screen the activities within.

In 2010, the Stonehenge Hidden Landscape Project discovered a "henge-like" monument less than away from the main site. This new hengiform monument was subsequently revealed to be located "at the site of Amesbury 50", a round barrow in the Cursus Barrows group.

In November 2011, archaeologists from University of Birmingham announced the discovery of evidence of two huge pits positioned within the Stonehenge Cursus pathway, aligned in celestial position towards midsummer sunrise and sunset when viewed from the Heel Stone.''Discoveries Provide Evidence of a Celestial Procession at Stonehenge''
, ''University of Birmingham Press Release, 26 November 2011 The new discovery was made as part of the Stonehenge Hidden Landscape Project which began in the summer of 2010. The project uses non-invasive geophysical imaging technique to reveal and visually recreate the landscape. According to team leader Vince Gaffney, this discovery may provide a direct link between the rituals and astronomical events to activities within the Cursus at Stonehenge.

In December 2011, geologists from University of Leicester and the National Museum of Wales announced the discovery of the source of some of the rhyolite fragments found in the Stonehenge debitage. These fragments do not seem to match any of the standing stones or bluestone stumps. The researchers have identified the source as a long rock outcrop called Craig Rhos-y-felin (), near Pont Saeson in north Pembrokeshire, located from Stonehenge.

In 2014, the University of Birmingham announced findings including evidence of adjacent stone and wooden structures and burial mounds near Durrington, overlooked previously, that may date as far back as 4000 BC. An area extending to was studied to a depth of three metres with ground-penetrating radar equipment. As many as seventeen new monuments, revealed nearby, may be Late Neolithic monuments that resemble Stonehenge. The interpretation suggests a complex of numerous related monuments. Also included in the discovery is that the cursus track is terminated by two wide, extremely deep pits, whose purpose is still a mystery.

An announcement in November 2020 stated that a plan to construct a four-lane tunnel for traffic below the site had been approved. This was intended to eliminate the section of the A303 that runs close to the circle. The plan had received opposition from a group of "archaeologists, environmentalists and modern-day druids" according to '' National Geographic'' but was supported by others who wanted to "restore the landscape to its original setting and improve the experience for visitors". Opponents of the plan were concerned that artifacts that are underground in the area would be lost or that excavation in the area could de-stabilize the stones, leading to their sinking, shifting or perhaps falling.

In February 2021, archaeologists announced the discovery of "vast troves of Neolithic and Bronze Age artifacts" while conducting excavations for a proposed highway tunnel near Stonehenge. The find included Bronze Age graves, late neolithic pottery and C-shaped enclosure on the intended site of the Stonehenge road tunnel. Remains also contained a shale object in one of the graves, burnt flint in C-shaped enclosure and the final resting place of a baby.

In January 2022, archaeologists announced the discovery of thousands of prehistoric pits during an electromagnetic induction field survey around Stonehenge. Based on the shape of the pits and the artifacts found inside, the study's lead author, Philippe De Smedt, assumed that six of the 9 large pits excavated were made by prehistoric humans. One of the oldest was about 10000 years old and contained hunting tools.

Origin of sarsens and bluestones

In July 2020, a study led by David Nash of the University of Brighton concluded that the large sarsen stones were "a direct chemical match" to those found at West Woods near Marlborough, Wiltshire, some 15 miles (25 km) north of Stonehenge. A core sample, originally extracted in 1958, had recently been returned. First the fifty-two sarsens were analysed using methods including x-ray fluorescence spectrometry to determine their chemical composition which revealed they were mostly similar. Then the core was destructively analysed and compared with stone samples from various locations in southern Britain. Fifty of the fifty-two megaliths were found to match sarsens in West Woods, thereby identifying the probable origin of the stones.

During 2017 and 2018, excavations by Professor Pearson's team at Waun Mawn, a large stone circle site in the Preseli Hills, suggested that the site had originally housed a diameter stone circle of the same size as Stonehenge's original bluestone circle, also orientated towards the midsummer solstice.

The circle at Waun Mawn also contained a hole from one stone which had a distinctive pentagonal shape, very closely matching the one pentagonal stone at Stonehenge (stonehole 91 at Waun Mawn / stone 62 at Stonehenge). Soil dating of the sediments within the revealed stone holes, via optically stimulated luminescence (OSL), suggested the absent stones at Waun Mawn had been erected around 3400–3200 BC, and removed around 300–400 years later, a date consistent with theories that the same stones were moved and used at Stonehenge, before later being reorganised into their present locations and supplemented with local sarsens as was already understood. Human activity at Waun Mawn ceased around the same time which has suggested that some people may have migrated to Stonehenge. It has also been suggested that stones from other sources may have been added to Stonehenge, perhaps from other dismantled circles in the region.

Further work in 2021 by Pearson's team concluded that the Waun Mawn circle had never been completed, and of the stones which might once have stood at the site, no more than 13 had been removed in antiquity.
