## Story

• A Neolithic henge and stone circles on a chalk ridge in the Kennet valley, with part of Avebury village still standing inside the bank.
• The ditch was cut with antler picks, and proposed dates for the main work run from about 3000 BC to about 2200 BC, with an older reading near 1700 BC.
• Paired stone avenues linked the circle to other monuments, including the Sanctuary, Silbury Hill, West Kennet Long Barrow, and Windmill Hill.
• Medieval villagers buried stones, a barber-surgeon with coins of the 1320s died under one of them, and many more stones were later broken for building.
• Twentieth-century digging recovered the antler picks and set fallen stones upright, while most of the interior remains unexcavated.

## Visiting

The henge and stone circles are open from dawn to dusk. Admission to the stone circles is free. Dogs are not allowed off a lead while sheep graze on the monument. Smoking, vaping, and naked flames are not allowed on the site.

## History

Avebury is a Neolithic henge on a low chalk ridge in the upper Kennet valley, about 160 metres above the sea and a few miles from Marlborough and Calne. A bank and an inner ditch enclose a great outer circle of sarsen stones and two smaller circles, and part of the village still stands among them. About 480 people live in Avebury, Avebury Trusloe, Beckhampton, and West Kennett.

The earthwork is not a true circle. One survey makes it 347.4 metres across and more than a kilometre round, another about 350 by 380 metres, and another gives the bank and ditch a circuit of 1.3 kilometres. The outer ring is called both the largest stone circle in Britain and the largest in the world. Counts of the original stones differ too: about 100 in the great circle, 98 in the outer ring, or 180 if the outer circle and the two inner circles are taken together.

Before the bank was built, snail shells and buried soils show oak woodland giving way to grassland. Pollen keeps poorly in the chalk, but tree pollen falls around 4500 BC and grasses increase toward 3200 BC. Flint tools of about 7000 to 4000 BC, including a knapping scatter some 300 metres west of the henge, show hunter-gatherers here long before the monument.

Farming, herds, and pottery arrived in the fourth millennium BC, and five patches of Neolithic activity lie within about 500 metres of the later circle. Communities in Wessex had, by about 3500 to 3300 BC, turned from expanding clearance and from great chambered tombs toward timber and stone circles. Avebury was one of several projects, not a single design, and it required a farming economy steady enough to spare the labour.

The order of those projects is disputed. One sequence places a cove near 3000 BC, an inner circle near 2900 BC, the outer circle and henge near 2600 BC, and the avenues near 2400 BC. Other dates put the henge in the middle of the third millennium BC, the stones between about 2870 and 2200 BC, or the whole building and rebuilding between about 2850 and 2200 BC. Pottery favours a later Neolithic main phase, and one set of dates points to major work around 4050 years before the present, while an early reading of the lowest pottery once suggested about 1700 BC.

The ditch was cut with red-deer antler picks. One excavation makes it about 11 metres deep, with a bank about 9 metres high. Another makes the ditch 12 to 15 metres wide and about 10 metres deep, with a bank up to about 6 metres.

Harold St George Gray dug the ditch in five seasons between 1908 and 1922. He found more than forty antler picks, scattered human bones, and the skeleton of a woman about 1.5 metres tall. The bank was raised in two phases, the second much larger, and it has four entrances.

The outer circle is 331.6 metres across. The northern inner circle is 98 metres across, with a three-sided cove open to the north-east. The southern circle was 108 metres across, with a central stone called the Obelisk and also described as 5.5 metres high, until much of it was destroyed in the eighteenth century. Avenues of paired stones ran toward the Sanctuary and, as digging in 1999 confirmed, toward Beckhampton.

No record says what the builders intended. Few pots or bones in the interior have been taken as a sign of restricted, careful use. Funerary rites, seasonal gatherings, a staged approach along the avenues, and a concern with the dead all remain possible. Windmill Hill, West Kennet Long Barrow, Silbury Hill, and the Sanctuary stand in the same landscape, and most of the 11 hectares inside the ditch has never been excavated.

By the Iron Age the henge seems little visited. Roman Britain, from 43 to 410 AD, brought travellers who left pottery in the ditch. North of the circle, ditches enclose an early Roman aisled building and deep shafts, with a smaller structure, a well in a sinkhole, coins, folded lead, and newborn burials read as a sanctuary. The shafts are given both as 9 metres deep and as 8.5 metres deep.

After Roman rule, the Anglo-Saxon settlement of Britain left only a light trace here: a sunken-floored hut outside the west bank in the sixth century, then a church in the tenth. A charter of King Athelstan in 939 mentions the neighbouring bounds of Overton.

Early in the fourteenth century villagers pulled stones down and buried them as the Devil's work. A man with coins of about 1320 to 1325, scissors, and a lancet was found in 1938 under a stone that had crushed him. The Black Death reached the village in 1349 and nearly halved it.

John Aubrey came on the stones while hunting in 1649 and showed them to Charles II in 1663. His plan records uprights that were soon afterwards heated, cracked with water, and broken for building.

William Stukeley measured the rings between 1719 and 1724, blamed the village for the destruction, and argued that druids had raised a temple there in 1859 BC. He altered some measurements to fit the idea and published that case in 1743. A rival account of 1723 had already called the rings Roman.

In the 1870s John Lubbock bought land inside the bank to stop new houses. Alexander Keiller (archaeologist) then bought some 950 acres, dug the avenues and the circle from 1934 to 1939, and set fallen stones upright, marking gaps with concrete. Isobel Smith published the full account in 1965.

Keiller sold the land in 1943 and died in October 1955. The landscape was inscribed in 1986, together with Stonehenge, as a World Heritage place of chalk downland.

Buried stones are still being found, including one estimated at more than 100 tons in 2003, and at least fifteen others mapped that year. Between the henge and the manor, recent trenches found almost no Neolithic settlement, which suggests the ground was kept clear while the monument was in use. The circle remains a broken but enormous ring, with a village inside it and most of its interior still unopened.

## Detailed history

Avebury is a henge of the Neolithic, the New Stone Age, standing in the upper valley of the River Kennet in Wiltshire. The earthwork sits on a low chalk ridge about 160 metres above the sea, some six miles from Marlborough and seven from Calne. It is not a perfect circle. One measured account gives the henge a diameter of 347.4 metres and a circuit of more than a kilometre. Another describes a ditch enclosing about 350 by 380 metres. A third gives the bank and ditch a circumference of 1.3 kilometres. Part of the living village lies inside the bank. About 480 people live in 235 homes in Avebury, the neighbouring settlement of Avebury Trusloe, and the hamlets of Beckhampton and West Kennett.

The henge holds three settings of local sarsen stone: a great outer circle and two smaller circles within it. The outer ring is described as the largest stone circle in Britain and, in other accounts, as the largest in the world. Those accounts do not agree on the original number of stones. One reckoning gives about 100 stones in the great circle. Another gives 98 sarsens in the outer ring, some weighing more than 40 tons and standing between 3.6 and 4.2 metres high. A wider count gives 180 unshaped local stones for the outer circle and the two inner circles together. Many of those stones have gone. By 1939 only nine of the outer stones were still upright, with another ten fallen, and the rest had been buried or broken up.

The Neolithic was the last division of the Stone Age, a long span in which farming, the keeping of animals, pottery, and settled life took hold in different parts of the world at different times. The name itself was coined in 1865. In Britain the shift gathered pace in the fourth millennium BC. Around Avebury the ground was not yet the open grassland a visitor sees now. Pollen keeps badly in the chalk, so the best evidence for the old vegetation is the shells of snails, each species tied to a particular habitat. Those shells, with buried soils, point to dense oak woodland in the early Neolithic, and then to a retreat of the trees and a spread of grass. Across lowland Britain a broader change in soils is placed around 4250 to 4000 BC, as clearance and farming turned damp forest earth chalkier. In the Mesolithic the woods were rich in alder, lime, elm, and oak. Tree pollen falls around 4500 BC, grasses increase until about 3200 BC, and cereal pollen appears.

Before the henge, the human trace is thin. The Mesolithic in Britain ran from about 11600 to 7800 years before the present, while the island was still heavily wooded and while a lowland, later drowned, still joined it to the continent. People then lived by hunting and gathering, moving in small groups. Stray flint tools around Avebury are dated between 7000 and 4000 BC. The clearest camp is a dense scatter of worked flint about 300 metres west of the henge, read as a place where a group of hunter-gatherers knapped stone over several weeks. A posthole near the southern entrance, found in the early twentieth century and never dated, has been suggested as a possible earlier marker, perhaps of the Late Mesolithic, because it does not line up with the later earthwork. That remains a suggestion. The hole could be centuries or millennia older than the bank, or it could belong to the building of the monument. What is firm is that people were already moving through this valley long before anyone dug the ditch.

In the fourth millennium BC domestic animals, cultivated plants, and pottery arrived, and people began to clear land and to raise the first monuments. Flint, animal bone, and pottery, including Peterborough ware of the early fourth and the third millennia BC, mark Neolithic activity at Avebury. Five distinct areas of that activity have been identified within about 500 metres of the henge, among them a scatter of flint along the later line of the West Kennet Avenue. The builders needed a farming economy stable enough to spare labour for work that did not feed them directly. That security is placed in Britain around 4000 to 3500 BC. Between about 3500 and 3300 BC, communities in the more productive regions, Wessex among them, stopped pushing clearance ever outward and settled to farm the land they already held. They also stopped raising the great chambered tombs associated with the honouring of ancestors, and over the next thousand years they built hundreds of timber and stone circles across Britain and Ireland.

Avebury was not designed in a single season. It is the sum of projects whose order is still argued. One proposed sequence puts a central cove at about 3000 BC, an inner stone circle at about 2900 BC, the outer circle and the henge at about 2600 BC, and the avenues at about 2400 BC. Radiocarbon dates place the henge by the middle of the third millennium BC, and some stone settings between about 2870 and 2200 BC. Another account says the henge was built and much altered roughly between 2850 and 2200 BC. Pottery of Windmill Hill, Peterborough, and Grooved Ware types, together with Beaker pottery, has come from various layers, and the balance of that pottery favours a later Neolithic date for the main construction. Dates taken from material kept from earlier digs have been said to mark a major phase around 4050 years before the present, though the full detail of those dates was still unpublished when that reading was set down. An early twentieth-century inspection of the ditch, judging the lowest pottery to be early Bronze Age or purely Neolithic, once offered a date near 1700 BC. The wider landscape of monuments around both Avebury and Stonehenge is given a longer span, about 3700 to 1600 BC in one account and about 4000 to 2400 BC in another. The stones may have gone up near the time when Silbury Hill was raised and when great works were also under way at Stonehenge and at Durrington Walls. That coincidence has been read as a possible surge of ceremonial building, a guess rather than a demonstrated revival.

The henge is a bank with an internal ditch, which is what the word means, and the ditch on the inside argues against a defensive purpose. There is a berm, now mostly lost to erosion, between bank and ditch. Four causewayed entrances break the circuit, at least three of them original, standing roughly north-north-west, east-north-east, south-south-east, and west-south-west. The bank was built in two phases, the later one on a much larger scale, a sequence first suspected when a trench was cut through the south-east bank in 1894. At a depth of about four feet that trench found a box-like structure of chalk blocks holding twenty large deer-horn picks, worn down by use, and three worked flints. The top of the bank is uneven. One explanation is that neighbouring gangs, cutting their own lengths of ditch, left an irregular crest. Others have argued that the uneven crest was a deliberate part of the Neolithic design.

The depth and width of the ditch are also given differently. The digging of 1908 to 1922 found more than forty antler picks on or near the bottom and took them as proof that the builders cut about 11 metres down into solid chalk with red-deer antlers as their main tools, leaving a bank about 9 metres high and a flat base about 4 metres wide. A workman was reported to have gone 17 feet below the silted bottom to reach the original floor, and the lowest pottery was then read as early Bronze Age or Neolithic. Later archaeologists have questioned whether untrained labour misread the profile, so the original shape may not have been exactly as drawn. A further measured account gives the ditch as originally 12 to 15 metres wide and about 10 metres deep, with an external bank originally up to about 6 metres high. Both accounts agree that the scale was enormous and that antler picks were among the tools left in the chalk.

Harold St George Gray directed those five seasons, in 1908, 1909, 1911, 1914, and 1922. He was born Harold Gray in Lichfield on 15 January 1872 and died on 28 February 1963. From 1888 he worked for Augustus Pitt Rivers, learned his methods of record, and later served as his secretary. He was assistant at the Pitt Rivers Museum in Oxford, then librarian-curator of the Somerset museum in Taunton until 1949. His wife, Florence Young, whom he married in 1899, worked with him in the field and on the finds. One account says the Avebury seasons were carried out for the British Association. Another says they were sponsored by the British Academy and by private donors. Gray found few objects in the ditch fill, but he did find scattered human bones, with jawbones especially well represented. At about two metres down he found the complete skeleton of a woman about 1.5 metres tall. He published the full report of the seasons in 1935. From 1926 to 1929 he also worked with Alexander Keiller at Windmill Hill, where the digging showed a causewayed enclosure and gave that class of monument its type-site for decades.

The outer circle follows the inner lip of the ditch and has a diameter of 331.6 metres. It was either contemporary with the earthwork or built some four or five centuries later. The two large stones at the southern entrance are unusually smooth, probably because stone axes were polished on them before or after they were set up. Many of the sarsens had a life before Avebury. Some had been used to grind axes, and others were heavily worked. They were not dressed into a common shape. They seem to have been chosen for the forms they already had. Tall slender stones and short squat stones have often been paired in theory as male and female, but that reading is a modern argument about Neolithic ideas of gender, not a fact recovered from the builders.

Closer to the middle stand two further circles. The northern ring is 98 metres across. Only two of its four recorded uprights remain standing. At its centre was a cove of three great slabs, open toward the north-east, forming three sides of a square with the fourth side left open. The southern ring was 108 metres across before its destruction in the eighteenth century, and what survives of its arc now lies under the houses. A single large stone stood at its centre. One account names that stone the Obelisk. Another gives its height as 5.5 metres. Smaller stones were aligned with it. Digging in the southern circle also found a line of stones that may have belonged to a sub-rectangular setting. In 2017 a geophysical survey by workers from Leicester and Southampton reported an apparently unique square megalithic monument inside the circles, possibly one of the earliest structures on the site. Antiquarian plans had implied still more rings, including a circle concentric with the outer ring and further settings in the north, but there is little physical evidence for them. A geophysical survey has, however, shown anomalies in the north-east that may mark a double ring of posts.

From two of the entrances, avenues of paired stones led out into the landscape. The West Kennet Avenue leaves the south-eastern entrance and runs toward the Sanctuary on Overton Hill, a distance given as more than two kilometres. The Beckhampton Avenue was drawn by eighteenth-century survey leaving the western entrance and running south-west. For a long time it was an open question whether that western avenue had ever existed. Excavation in 1999 confirmed it. It is thought to have been built toward the end of the late Neolithic burst of building, to run about 1.5 kilometres west, and to link the henge to the Longstones Cove. A geophysical survey in 2022 mapped a further stretch of about 120 metres and was published in 2024, showing both the form of that length and what became of the stones that once stood there.

The purpose of the henge is unknown. The scarcity of pottery and animal bone has been taken to mean that the entrance was restricted and that the interior was treated as a place apart. A meeting ground for seasonal gatherings remains possible, with people watching from the bank. Human bones in the ditch, including the woman Gray found, point to some funerary use and echo the disarticulated bones known from earlier causewayed enclosures, so honouring the dead on a large scale is another reading, and it need not cancel any other. Rituals at the turning of the year, meant to hold off winter, death, and disease, have been proposed as well. Circles of stone and timber elsewhere in Britain have been understood as a centre of the world for their builders, an idea taken from the study of Orcadian rings and offered as one possibility here. Sound made inside the inner circles may have returned as an echo off the stones, a suggestion drawn from experiments at the Ring of Brodgar. The avenues have been read as carefully staged paths, controlling how a person moved and what they saw, and tying Avebury to the Sanctuary, to Silbury Hill, and to the West Kennet Long Barrow. Digging the ditch and throwing the chalk up into the bank has been imagined as turning the land inside out, a space on the edge between the world above and the world below. None of these readings is secured by a written record. The builders left none.

Avebury stands in a landscape already old when the great circle was raised. Windmill Hill, a causewayed enclosure, holds thick deposits of animal bone and is understood as a place of gathering and feasting that drew people from beyond the immediate district. West Kennet Long Barrow is a stone-chambered collective tomb, the largest of its kind known in southern England. Silbury Hill, the largest prehistoric mound in Europe, is placed around 2400 BC, stands 39.5 metres high, and is said to contain half a million tonnes of chalk. Its purpose is obscure. The Sanctuary, the avenues, and a scatter of barrows complete a group that has been called a ritual complex, a set of monuments with interlocking roles. The same kind of oversized henge, with unusual entrances and internal settings, is shared in some degree with Durrington Walls and Marden in Wiltshire and with Mount Pleasant in Dorset. The name henge enclosure has been suggested for that small class. Less than ten such enclosures are firmly identified, all of them in Wiltshire and Dorset. They lie low, on gentle slopes by water, and each may have served as the focus of a territory. Most of the interior at Avebury, an area given as about 11 hectares inside the ditch, has never been excavated, and the ground outside the enclosure has barely been touched.

By the Iron Age the monument seems to have lost its original use. There is little sign that many people visited it. Later inhabitants may not have known who built it, or when, or why. Southern Britain then entered the Roman Empire. Roman Britain, the province of Britannia, lasted from the invasion of 43 AD until 410 AD. Julius Caesar had landed in 55 and 54 BC, taken tribute, and left. In 43 AD the emperor Claudius sent four legions, defeated the Catuvellauni, and began the province. Visitors in the centuries that followed came to Avebury from the towns of Cunetio and Durocornovium and from villas and farms around Devizes, using a new road, and Roman pottery was left in the ditch. North of the henge, in ordinary pasture by the Winterbourne stream, recent digging has shown that the valley was still a place of ritual long after the sarsens were raised. Geophysics found three parallel ditches of the Roman period enclosing about 80 by 40 metres, with an entrance toward the marshy stream. Inside, four years of excavation revealed an aisled building about 20 by 12 metres from the early years of the occupation, and two circular shafts or springheads. One account gives those shafts as 9 metres deep. A later account of the same site, where work has continued from 2021, describes three shafts or wells, two of them 8.5 metres deep, and says that at least two of the three ditches were used in succession. A smaller rectangular building in the north-west corner of the enclosure produced a clipped fragment of a Roman coin and pieces of folded lead, and a well had been built in the bottom of a natural sinkhole beside it. The 2025 season uncovered a monumentalised entrance, the filling of one perimeter ditch, and a sarsen revetment at the edge of the Winterbourne wetland, probably of the middle imperial period. Specialist work has noted many bones of dogs and horses, at least four newborn human remains, and pottery of the fifth and fourth centuries BC in some contexts. The newborn remains near the small building have been taken to support a reading of the place as a sanctuary, and of that building as an altar or a shrine. The same landscape was therefore still being visited, interpreted, and treated as holy centuries after the henge was dug.

After Roman rule ended in the early fifth century, the Anglo-Saxon settlement of Britain brought Germanic-speaking people from across the sea into southern Britain, and an Anglo-Saxon identity took shape. The first of those speakers who stayed may have been soldiers recruited while the province still stood, in the fourth century or earlier. Larger numbers arrived as Roman government and the Roman economy broke down. How large the migration was, and what became of the people already living here, is still debated. Medieval texts stress Saxon settlement and violence in the fifth century, but they are short on reliable detail. At Avebury itself the early medieval evidence is modest. A grubenhaus, a timber hut with a sunken floor, was built just outside the west bank in the sixth century. Only a few farmers seem to have lived here, and they left the stones largely alone. Their pagan religion honoured several gods, notably Woden and Thunor. Within about ten miles, four names seem to remember Woden: Wansdyke, Woden's Barrow, Waden Hill, and perhaps Wanborough. It is not known whether they gave the henge a god of its own. A suggestion from the place-name evidence is that the site was once called weala-dic, the moat of the Britons, and that a small British force might have used the old earthwork against Anglo-Saxon attack. That is a suggestion from a name, not a recorded siege. In the seventh and eighth centuries conversion to Christianity spread, and in the tenth century a church was built just west of the monument. The earliest known writing that touches the monument is a charter of King Athelstan in 939, setting the bounds of Overton, the next parish. In the following century Viking armies from Denmark fought Anglo-Saxon groups in the district. Silbury Hill was fortified, apparently by local people defending themselves, and the village at Avebury may have been destroyed then.

By the later Middle Ages the stones had been given to the Devil in local speech. The largest stone at the southern entrance was the Devil's Chair. The three stones of the Beckhampton cove were the Devil's Quoits. The stones of the north circle were the Devil's Brand-Irons. Early in the fourteenth century villagers began to pull the great uprights down and bury them in pits dug ready beside them. The likely motive was religious: a Christian village had come to see the ring as the Devil's work. Who urged the demolition is unknown. The parish priest of those years may have been Thomas Mayn, who served from 1298 to 1319, or John de Hoby, who served from 1319 to 1324. In 1938, under a fallen stone, excavators found the skeleton of a man. The stone is numbered 38 in one system and 9 in the numbering Isobel Smith later imposed. He had a leather pouch with three silver coins dated to around 1320 to 1325, a pair of iron scissors, and a lancet, the tools of a travelling barber-surgeon who worked the market towns. The coins are also described as dating from the 1320s. He seems to have been killed when the stone fell on him as he dug the hole in which it was to be buried, a medieval rite of destruction that went wrong. The death appears to have stopped the toppling for a time. Stories of a man crushed by a stone were still told in the eighteenth and nineteenth centuries. The Black Death, the plague pandemic that ran through Europe from 1346 to 1353 and killed a very large part of the population, reached the village in 1349 and almost halved it. Survivors turned to growing food. They had neither time nor labour to start the demolition again.

Antiquarian notice began in the sixteenth century. Around 1541 John Leland, librarian and chaplain to Henry VIII, passed through Wiltshire and noted Avebury and the monuments nearby. William Camden's Latin survey of British antiquities, issued in 1586, ignored it. His English edition of 1610 mentioned Abury only in passing, as an old camp. A note of 1634 in Sir John Harington's commentary mentioned it again. Then the English Civil War cut investigation short. That war, also called the Great Rebellion, was fought between Royalists and Parliamentarians from 1642 to 1651, inside the wider Wars of the Three Kingdoms, over the balance of power between Parliament and Charles I. One of its battles was fought at Roundway Down, about five miles from the village. John Aubrey, born at Easton Piercy in Wiltshire on 12 March 1626, had gone up to Trinity College, Oxford, in 1642, and the war interrupted his studies. He was a Wiltshire gentleman, educated at Malmesbury and Blandford, later a student of the Middle Temple, and an apolitical Royalist. In 1649, out hunting, he came on the stones and was, in his own words, wonderfully surprised at the sight of those vast stones, of which he had never heard. His father died in 1652 and left him estates tangled with debt. Aubrey published little in his lifetime. His Brief Lives, short biographies of his contemporaries, later made him look to many readers like a gossip, and only from the 1970s was the range of his scholarship widely recognised. He is the man for whom the Aubrey holes at Stonehenge are named, though it is doubtful whether the holes he saw are the ones that now carry the name.

In July 1663 Charles II, having heard of Avebury, had Aubrey describe it, and a fortnight later, on the king's journey to Bath, the two visited the site together. The king ordered Aubrey to dig beneath the stones for burials. Aubrey never did. In September 1663 he began a more systematic survey and drew a plan that later archaeologists have treasured, because it marks standing stones that villagers destroyed soon afterwards. His Monumenta Britannica records the henge among many other field monuments he was often the first to write down. He also gathered folklore under the title Remaines of Gentilisme and Judaisme, and he attempted unfinished county histories of Wiltshire and Surrey. Destruction at the henge peaked in the later seventeenth century and the eighteenth, perhaps encouraged by Puritan hostility to anything counted pagan. Stones that had stood for thousands of years were broken for building. The method was to heat a sarsen with fire, crack it with cold water, and finish it with a sledgehammer.

William Stukeley watched that destruction. He was born at Holbeach in Lincolnshire on 7 November 1687, the son of a lawyer, and he died on 3 March 1765. He trained in medicine, practised in Boston, and from 1710 to 1725 toured the country recording monuments. In 1718 he became a Fellow of the Royal Society and the first secretary of the Society of Antiquaries. He was ordained in 1729 and made vicar of All Saints in Stamford, encouraged by Archbishop William Wake to turn antiquarian study against deism. He answered by arguing that the ancient druids had followed a monotheistic faith inherited from the biblical patriarchs, a religion he called Patriarchal Christianity, and that they had raised stone circles as serpentine temples of the Trinity. He visited Avebury six times between 1719 and 1724, sometimes staying two or three weeks at the Catherine Wheel inn, and he measured the rings with a care that later fieldwork still respects. He called the place a British temple, dated the druids' work to 1859 BC, took the two inner circles for temples of the moon and the sun, and came to see the whole landscape as a figure of the Trinity. He was disgusted by the smashing of the sarsens, named the farmers and builders responsible, and wrote that the fabric, which might have lasted as long as the globe, had fallen to the ignorance and avarice of a little village unluckily placed within it. In 1743 he published that case. He also altered some of his own measurements so that the plan would fit the theory. His friend the Reverend Thomas Twining had already published, in 1723, an argument that the rings were Roman. Twining's reason was that Julius Caesar and Tacitus did not mention stone circles when they wrote about Iron Age Britons, whereas later medieval historians such as Geoffrey of Monmouth and Henry of Huntingdon did, so the monuments, he thought, must fall between those writings. Stukeley's druidic chronology was largely rejected by archaeologists in the later nineteenth century. What survived of his work was the habit of measuring and drawing. He also recorded, before 1725, the avenue at Shap in Cumbria, a monument since mostly destroyed, whose surviving end at Kemp Howe has been compared with the Sanctuary. He thought Shap another serpentine temple on the Avebury pattern.

Through the Victorian years the village grew and more houses went up inside the bank. Most of the Neolithic uprights had already gone, buried in the fourteenth century or broken in the seventeenth and eighteenth. In 1865 a week of digging in fourteen places, including the cove, supported by the county archaeological society, found no human bones. In 1833 Henry Browne had claimed evidence of burnt human sacrifice at the cove, and in 1829 the foot of the cove stone had been dug to a depth of a yard. In the 1870s Sir John Lubbock, later Baron Avebury, the same man who in 1865 had coined the word Neolithic, bought much of the land inside the monument to stop further building, and he urged others to put their houses outside the bank.

Alexander Keiller (archaeologist) made the modern appearance of the circle. He was born in Dundee on 1 December 1889, the only child of John Mitchell Keiller and Mary Sime Greig, and the heir to James Keiller and Son, a marmalade house founded in Dundee in 1797. His father died when he was nine and his mother when he was seventeen. He was schooled at Hazelwood and at Eton, then ran the family business. In the First World War he served in the Royal Naval Volunteer Reserve and the Royal Naval Air Service, was invalided out, and returned to air intelligence in 1918. In 1922 he and O. G. S. Crawford surveyed archaeological sites from the air across south-western England, and in 1928 they published a book of that survey which has been identified as the first book of aerial archaeology issued in Britain. He bought Windmill Hill and dug it with Harold St George Gray. His second wife, Veronica Mildred Liddell, whom he married in 1924 and divorced in 1934, supervised there with her sister Dorothy Liddell. He decided that the way to preserve Avebury was to buy it. Between 1924 and 1939 he acquired a large part of the circle, as much of the Kennet Avenue as he could, Windmill Hill, and Avebury Manor, where he lived until his death. In all he gathered 950 acres. He founded the Morven Institute of Archaeological Research, the ancestor of the museum that now bears his name.

His excavations ran along the West Kennet Avenue in 1934 and 1935, through the north-west sector of the circle in 1937, the south-west in 1938, and the south-east in 1939. Stuart Piggott co-directed. William E. V. Young was foreman. Doris Emerson Chapman, an artist whom Keiller married in 1938 and divorced in 1951, drew the stones and made facial reconstructions from skulls. Denis Grant King drew the plans and sections. More than fifty local men did the digging and the lifting. Keiller had fallen and buried stones found and set upright again, and he marked missing stones with concrete pylons. The outbreak of war, his failing health, his shrinking funds, and Piggott's move into other work meant that the two of them never published a full report. Short accounts appeared. Gabrielle Keiller, his fourth wife, whom he married late and who survived him, later commissioned Isobel Smith to finish the record. Smith published it in 1965, renumbered the stones, and set Windmill Hill, the henge, and the West Kennet Avenue in one sequence. Keiller died in October 1955. An obituary by Piggott wrongly put the death in September. In 1943 he had sold the Avebury land for its agricultural value only. In 1966 Gabrielle gave the museum and its contents to the nation.

Denis Grant King was born on 6 April 1903 at Honor Oak Park in Kent and died in Devizes on 23 February 1994. His father was an artist who lived by advertising, and Denis trained at the Blackheath School of Art. From 1938 to 1941 he was surveyor and draftsman at Avebury. His measured drawings were accurate enough to guide the resetting of fallen stones. He also kept a diary of the dig and drew cartoons for the crew. A conscientious objector in wartime, he was first set to look after poultry at an evacuated school and then allowed to teach history and archaeology. After the war he worked for Isobel Smith at Windmill Hill, and later he led his own digs, among them Bury Camp, an Iron Age hillfort near North Wraxall, in 1959, with a volunteer crew he called the Bury Wood Excavation Club, and Lanhill long barrow in 1963. John Aubrey had recorded Lanhill in 1647. Quarrying and rough clearance, including a bulldozer, had damaged it, and King complained until he could record and partly rebuild what remained. In 1972 he called a conference to protect the Ridgeway from traffic, and he fought a road scheme that would have cut into Durrington Walls.

The museum Keiller began stands in the seventeenth-century stables, with a permanent display in the nearby threshing barn. Its core is the material he brought in 1938 from his London house in Charles Street, mostly Neolithic and early Bronze Age, with later Anglo-Saxon pieces. It includes the skeleton of a child, nicknamed Charlie, found in a ditch on Windmill Hill. In 2006 the Council of British Druid Orders asked that the child be reburied. In April 2010 the decision was to keep the skeleton on public view. Faith Vatcher was curator from the middle of the 1960s until her death in 1978, and she was closely involved in digging on the west side of the henge in 1969, when a new village school was built, and in 1976 on the ground that is now the visitor car park. Caroline Malone, born in 1957, was curator of the museum from 1985 to 1987 and then an inspector of ancient monuments from 1987 to 1990. She has described the monuments of Avebury and Stonehenge as possible ritual or ceremonial centres, and she has suggested that the irregular crest of the bank came from the uneven work of the ditch gangs. She later became professor of prehistory at Queen's University Belfast.

Other seasons were smaller. In 1960 Stuart Piggott spent five days opening about 1,500 square feet in search of stone holes and found none. In 1982 a dig was cut to recover material for radiocarbon dating and for environmental study. In April 2003, while some stones were being straightened, one was found to run at least 2.1 metres below the surface and was estimated at more than 100 tons, among the largest known in Britain. Later that year a geophysical survey of the south-east and north-east quadrants found at least fifteen further megaliths still buried, and recorded their size, the way they were lying, and where they belonged in the ring.

Alexander Thom, a Scottish engineer born at Carradale on 26 March 1894 and dead on 7 November 1985, spent decades surveying stone circles with a theodolite and argued for a standard prehistoric unit, the megalithic yard, first proposed in his work of 1955. He classed circles by shape and suggested that some were astronomical instruments, able to predict eclipses on a nineteen-year cycle and tied to a solar calendar. He also proposed a site-to-site alignment at Avebury involving the star Deneb. Aubrey Burl, born on 24 September 1926 and dead on 8 April 2020, who taught archaeology at Hull and wrote a study of prehistoric Avebury published in 1979, treated astronomical roles as possible but was wary of the more fragile claims. He preferred to see henges and circles as places of ritual bound up with death, fertility, and ancestors, used at points in the year such as the spring equinox and the summer solstice, on the pattern of rites in other farming societies, rather than as observatories staffed by astronomer-priests. His suggested building sequence for Avebury is the one that places the cove near 3000 BC and the avenues near 2400 BC. He also thought Iron Age people here would have inherited the ring without a clear memory of its makers, and he was among those who doubted the more romantic stories attached to it.

Empty houses inside the circle were taken down as they fell vacant after the land was sold in 1943, until 1976, when the houses still occupied were allowed to stay. The whole Stonehenge and Avebury landscape was inscribed in 1986. Each of the two chalkland blocks is about 25 square kilometres in one description, while the Avebury monuments themselves are given as covering about 23 square kilometres. In 2008 the Avebury boundary was extended to take in East Kennet Long Barrow and Fyfield Down, with its Bronze Age fields and its natural sarsens. Roads still cut the henge and the West Kennet Avenue, and a main road separates the Sanctuary from the barrow group on Overton Hill. The noise and the traffic are recognised as a harm to the setting. Even so, the earth and the surviving stones keep their materials and their design, and the re-erection of fallen stones in the early and middle twentieth century was done to make that design readable again. By the late 1970s about a quarter of a million people a year were coming.

The henge has also become a place of worship for present-day pagans, including followers of Druidry, Wicca, and Heathenry, who treat it as a living temple linked to ancestors and to the spirits of the place. Public rites, especially at the summer solstice, draw crowds of onlookers. Druid ceremonies here are called gorseddau. They call on Awen, inspiration, and include an eisteddfod of poems, songs, and stories. The Druid prayer written by Iolo Morganwg in the eighteenth century is commonly recited. One group, the Gorsedd of Bards of Caer Abiri, works almost only at this site and calls it Caer Abiri. A ceremony composed in 1993 by Philip Shallcrass divides the assembly into a party of the Goddess and a party of the God. The Goddess party goes to the Devil's Chair, where a woman sits as guardian of the place, and the God party walks the outer bank and offers flowers, fruit, bread, or mead. A rota shares the circle among several orders on Saturdays and Sundays. Some visitors also walk the ring with dowsing rods. These are modern religious uses. They are not evidence for what the Neolithic builders believed.

Fresh fieldwork continues to change the map of settlement. Between the henge and the manor, digging finished in 2024 that had been started to find Neolithic houses found very little Neolithic material at all. The surprise has been read as a sign that this ground was kept clear while the monument was in use, a reserved space rather than a village. The same trenches did find Mesolithic worked flint, and later traces of the medieval village and of the manor after 1550, up to the making of a formal park around 1700. About four kilometres west, at Cherhill, a later Mesolithic tufa spring preserved footprints of wild cattle and deer in what had been soft mud, together with flint tools, butchered bone, and antler, a level of preservation unusual for that age in Britain. A nearby hollow held Middle Neolithic refuse, worked flint, bone, and pottery, close in time to the first monumental phases. Whether any of those people helped to build Avebury is an open question, not a demonstrated fact. What the trenches do show is a valley used, in different ways, from hunter-gatherer camps to Roman shrines to a medieval village that grew into the stones and then tried, for a while, to put them underground.

The henge and the stone circles are open from dawn to dusk, and entry to them is free. Sheep often graze the grass, and dogs are not allowed off a lead. Smoking, vaping, and naked flames are not allowed on the monument. The museum, the manor, and the garden are separate visits, with their own hours and tickets. What remains in the circle is a bank, a silted ditch, a broken but still enormous ring of sarsens, two inner settings, the lines of the avenues, and a village that has lived among the stones since the early Middle Ages. Most of the ground inside the ditch has never been opened. The buried stones, the undug interior, and the Roman sanctuary by the Winterbourne are reminders that the record of this place is still incomplete, and that each generation since John Aubrey has had to correct the picture drawn by the one before.
