The Coldrum Long Barrow, also known as the Coldrum Stones and the Adscombe Stones, is a chambered long barrow located near to the village of Trottiscliffe in the southeastern English county of Kent. Constructed circa 4000 BCE, during Britain's Early Neolithic period, today it survives only in a ruined state.
Archaeologists have established that the monument was built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe. Although representing part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, the Coldrum Stones belong to a localised regional variant of barrows produced in the vicinity of the River Medway, now known as the Medway Megaliths. Of these, it is in the best surviving condition, and lies near to both Addington Long Barrow and Chestnuts Long Barrow on the western side of the river. Three further surviving long barrows, Kit's Coty House, the Little Kit's Coty House, and the Coffin Stone, are located on the Medway's eastern side.
Built out of earth and around fifty local sarsen megaliths, the long barrow consisted of a sub-rectangular earthen tumulus enclosed by kerb-stones. Within the eastern end of the tumulus was a stone chamber, into which human remains were deposited on at least two separate occasions during the Early Neolithic. Osteoarchaeological analysis of these remains has shown them to be those of at least seventeen individuals, a mixture of men, women, children and adults. At least one of the bodies had been dismembered prior to burial, potentially reflecting a funerary tradition of excarnation and secondary burial. As with other barrows, Coldrum has been interpreted as a tomb to house the remains of the dead, perhaps as part of an ancestor cult, although archaeologists have suggested that it may also have had further religious, ritual, and cultural connotations and uses.
After the Early Neolithic, the long barrow fell into a state of ruined dilapidation, perhaps being largely demolished by Christian zealots in the late 13th or early 14th century CE. Local folklore grew up around the site, associating it with the burial of a prince and the countless stones motif. The ruin attracted the interest of antiquarians in the 19th century, while archaeological excavation took place in the early 20th. After limited reconstruction, in 1926 ownership was transferred to heritage charity The National Trust. It is open without charge to visitors all year around.

Name and location
The Coldrum Stones are named after a nearby farm, Coldrum Lodge, which has since been demolished. The monument lies in a "rather isolated site" north-east of the nearby village of Trottiscliffe, about 500 metres from a prehistoric track known as the Pilgrim's Way. The tomb can be reached along a pathway known as Coldrum Lane, which is only accessible on foot. The nearest car park to Coldrum Lane can be found off of Pinesfield Lane in Trottiscliffe. Another nearby village is Addington, which is located one and a quarter miles away.
Early Neolithic Britain
The Early Neolithic was a revolutionary period of British history. Beginning in the fifth millennium BCE, it saw a widespread change in lifestyle as the communities living in the British Isles adopted agriculture as their primary form of subsistence, abandoning the hunter-gatherer lifestyle that had characterised the preceding Mesolithic period. Archaeologists have been unable to prove whether this adoption of farming was because of a new influx of migrants coming in from continental Europe or because the indigenous Mesolithic Britons came to adopt the agricultural practices of continental societies. Either way, it certainly emerged through contact with continental Europe, probably as a result of centuries of interaction between Mesolithic people living in south-east Britain and Linear Pottery culture (LBK) communities in north-eastern France. The region of modern Kent would have been a key area for the arrival of continental European settlers and visitors, because of its position on the estuary of the River Thames and its proximity to the continent.
Between 4500 and 3800 BCE, all of the British Isles came to abandon its former Mesolithic hunter-gatherer lifestyle, to be replaced by the new agricultural subsistence of the Neolithic Age. It is apparent that although a common material culture was shared throughout most of the British Isles in this period, there was great regional variation regarding the nature and distribution of settlement, architectural styles, and the use of natural resources. Throughout most of Britain, there is little evidence of cereal or permanent dwellings from this period, leading archaeologists to believe that the Early Neolithic economy on the island was largely pastoral, relying on herding cattle, with people living a nomadic or semi-nomadic way of life. Archaeologists have no direct proof of gender relations on the island at this time, although most believe that it was probably a male-dominated society, in keeping with all recorded societies that practice large-scale animal husbandry. There is archaeological evidence of violence and warfare in Early Neolithic Britain from such archaeological sites as West Kennet Long Barrow and Hambledon Hill, with some groups constructing fortifications to defend themselves from attackers.
Britain was largely forested in this period, although did witness some land clearance. It remains unclear to what extent the Kentish area was deforested in the Early Neolithic, although it appears that widespread forest clearance only took place on the chalklands of south-east Britain much later, in the Late Bronze Age. Environmental data from the area around the White Horse Stone supports the idea that the area was still largely forested in the Early Neolithic, covered by a woodland of oak, ash, hazel/alder and Maloideae.
The tomb building tradition
Across Western Europe, the Early Neolithic marked the first period in which humans built monumental structures in the landscape. These were tombs that held the physical remains of the dead, and though sometimes constructed out of timber, many were built using large stones, now known as "megaliths". Individuals were rarely buried alone in the Early Neolithic, instead being interned in collective burials with other members of their community. The construction of these collective burial monumental tombs, both wooden and megalithic, began in continental Europe before being adopted in Britain in the first half of the fourth millennium BCE.
The Early Neolithic people of Britain placed far greater emphasis on the ritualised burial of the dead than their Mesolithic forebears had done. Many archaeologists have suggested that this is because Early Neolithic people adhered to an ancestor cult that venerated the spirits of the dead, believing that they could intercede with the forces of nature for the benefit of their living descendants. Archaeologist Robin Holgate stressed that rather than simply being tombs, the Medway Megaliths were "communal mouments fulfilling a social function for the communities who built and used them." Thus, it has furthermore been suggested that Early Neolithic people entered into the tombs – which doubled as temples or shrines – to perform rituals that would honour the dead and ask for their assistance. For this reason, historian Ronald Hutton termed these monuments "tomb-shrines" to reflect their dual purpose.
In Britain, these tombs were typically located on prominent hills and slopes overlooking the surrounding landscape, perhaps at the junction between different territories. Archaeologist Caroline Malone noted that the tombs would have served as one of a variety of markers in the landscape that conveyed information on "territory, political allegiance, ownership, and ancestors." Many archaeologists have subscribed to the idea that these tomb-shrines served as territorial markers between different tribal groups, although others have argued that such markers would be of little use to a nomadic herding society. Instead it has been suggested that they represent markers along herding pathways. Many archaeologists have suggested that the construction of such monuments reflects an attempt to stamp control and ownership over the land, thus representing a change in mindset brought about by Neolithicisation. Others have suggested that these monuments were built on sites already deemed sacred by Mesolithic hunter-gatherers.
Archaeologists have differentiated these Early Neolithic tombs into a variety of different architectural styles, each typically associated with a different region within the British Isles. Passage graves, characterised by their narrow passage made of large stones and one or multiple burial chambers covered in earth or stone, were predominantly located in northern Britain and southern and central Ireland. Alternately, across northern Ireland and central Britain long chambered mounds predominated, while in the east and south-east of Britain, earthen long barrows represented the dominant architectural trend. These earthen long barrows were typically constructed of timber because building stone was scarce in southern Britain; archaeologist Aubrey Burl argued that these timber tombs might have been "even more eye-catching" than their stone counterparts, perhaps consisting of "towering carved poles, flamboyantly painted", but that evidence of such sculptures has not survived. The Medway Megaliths represent just one of these regional groups within the wider West European tradition of tomb building in this period.
The Medway Megaliths
Although now all in a ruinous state and not retaining their original appearance, at the time of construction the Medway Megaliths would have been some of the largest and most visually imposing Early Neolithic funerary monuments in Britain. Grouped along the River Medway as it cuts through the North Downs, they constitute the most south-easterly group of megalithic monuments in the British Isles, and the only megalithic group in eastern England. Archaeologists Brian Philp and Mike Dutto deemed the Medway Megaliths to be "some of the most interesting and well known" archaeological sites in Kent, while archaeologist Paul Ashbee described them as "the most grandiose and impressive structures of their kind in southern England". The BBC Countryfile website notes that although none of the monuments are on the same scale as Stonehenge, they are "really quite impressive" when taken collectively, describing them as "the east of England's answer to the megaliths of the Salisbury Plains".
They can be divided into two separate clusters: one to the west of the River Medway and the other on Blue Bell Hill to the east, with the distance between the two clusters measuring at between 8 and 10 km. The western group includes Coldrum Long Barrow, Addington Long Barrow, and the Chestnuts Long Barrow. The eastern group consists of Kit's Coty House, Little Kit's Coty House, the Coffin Stone, and several other stones which might have once been parts of chambered tombs. It is not known if they were all built at the same time, or whether they were constructed in succession, while similarly it is not known if they each served the same function or whether there was a hierarchy in their usage.
The Medway long barrows all conformed to the same general design plan, and are all aligned on an east to west axis. Each had a stone chamber at the eastern end of the mound, and they each probably had a stone facade flanking the entrance. The chambers were constructed from sarsen, a dense, hard, and durable stone that occurs naturally throughout Kent, having formed out of silicified sand from the Eocene. Early Neolithic builders would have selected blocks from the local area, and then transported them to the site of the monument to be erected.
Such common architectural features among these tomb-shrines indicate a strong regional cohesion with no direct parallels elsewhere in the British Isles. For instance, they would have been taller than most other tomb-shrines in Britain, with internal heights of up to 10 ft. Nevertheless, as with other regional groupings of Early Neolithic tomb-shrines (such as the Cotswold-Severn group), there are also various idiosyncrasies in the different monuments, such as Coldrum's rectilinear shape, the Chestnut long barrow's facade, and the long, thin mounds at Addington and Kit's Coty. This variation might have been caused by the tomb-shrines being altered and adapted over the course of their use; in this scenario, the monumnets would represent composite structures.
It seems apparent that the people who built these monuments were influenced by pre-existing tomb-shrines that they were already aware of. Whether those people had grown up locally, or moved into the Medway area from elsewhere is not known. Based on a stylistic analysis of their architectural designs, Stuart Piggott thought that they had originated in the area around the Low Countries, while Glyn Daniel instead believed that the same evidence showed an influence from Scandinavia. John H. Evans instead suggested an origin in Germany, and Ronald F. Jessop thought that their origins could be seen in the Cotswold-Severn megalithic group. Ashbee noted that their close clustering in the same area was reminiscent of the megalithic tomb-shrine traditions of continental Northern Europe, and emphasised that the Medway Megaliths were a regional manifestation of a tradition widespread across Early Neolithic Europe. He nevertheless stressed that a precise place of origin was "impossible to indicate" with the available evidence.
Design and construction
The monument originally consisted of a sarsen stone chamber, covered by a low earthen mound, which was bounded by prostrate slabs. As such, the archaeologist Paul Ashbee asserted that the monument could be divided into three particular features: the chamber, the barrow, and the sarsen stone surround. It is located on the edge of a large lynchet scarp, although it is difficult to ascertain what views would have been possible from the monument at the time of construction, due to a lack of information on how densely forested the vicinity was. However, if the area was not highly wooded, then 360° views of the surrounding landscape would have been possible. The monument's axis points toward both the North Downs and the Medway Valley, which is similar to the other Medway Megaliths. Archaeologist Sian Killick suggested that the Coldrum Long Barrow might have been built within view of a nearby settlement, and that this "may have been a key factor in the experience of ceremonies and rituals taking place at the tombs and may also have defined a link between the tomb builders and the landscape."
It had been built using about 50 stones. The barrow is sub-rectangular in plan, and about 20 meters (64 feet) in length. At its broader, eastern end, where the chamber is located, the monument measures 15 metres (50 feet), while at the narrower, western end, it is 12 metres (40 feet) in breadth. As such, the barrow is a "truncated wedge-shape". The megalithic builders responsible for the Coldrum Stones positioned it on the top of a small ridge adjacent to the North Downs, and constructed it facing eastward, towards the River Medway.
The chamber of the monument measures 4.5 metres (13 feet) in length, and 1.7 metres (5 feet 6 inches) in width, although it was potentially much larger when originally constructed. The chamber's internal height would have been at least 2 metres (6 feet 6 inches). In its current state, the northern side of the chamber is made up of two slabs, one being 8 feet long, 7 feet, 6 inches deep, and 1 foot, 9 inches thick, and the other 5 feet long, 6 feet deep, and 2 feet thick. Conversely, the chamber's southern side consists of a single slab, measuring 11 feet, 4 inches in length, 7 feet, 3 inches in depth, and 1 foot, 9 inches in depth at its thicker, eastern end. The western end of the chamber is closed off with a slab measuring about 14 feet, 6 inches wide, with a thickness of 1 foot and a depth of around 8 feet. A collapsed, broken slab lies at the opening eastern end of the chamber. It is also possible that a largely rectangular slab at the bottom of the slope had once been part of the eastern end of the chamber. Excavation has revealed that flint masonry was used to pack around the chamber and support its sarcens; twentieth-century renovation has seen this largely replaced with cement, allowing the stones to continue standing upright.
It is possible that there was a facade in front of the chamber, as is evident at other chambered tombs in Britain, such as West Kennet Long Barrow and Wayland's Smithy. It is also possible that there was a portal stone atop the chamber, as was apparent at Kit's Coty House and Lower Kit's Coty House. Many of the larger slabs of stone that have fallen down the slope on the eastern end of the monument may have been parts of this facade or portal.
The earthen mound that once covered the tomb is now visible only as an undulation approximately 1 foot, 6 inches in height. In the nineteenth-century, the mound was higher on the western end of the tomb, although this was removed by excavation to reveal the sarsens beneath during the 1920s. It is likely that in the Early Neolithic, the mound had a quarry ditch surrounding it, and it is inside this ditch that the kerb-stones now sit.
The kerb-stones around the tomb display some patterning; those on the northern side are mostly rectilinear, while those on the southern side are smaller and largely irregular in shape. It is probable that there was an ancillary dry-stone wall constructed using blocks of ironstone from the geological Folkestone beds, as is evident at Chestnuts Long Barrow. Given that such blocks of stone rarely occur naturally, it may have been quarried.
A concave line of abrasion and polishing can be found on both one of the central kerb-stones on the western end of the monument and a kerb-stone on the south-east of the monument. These have been attributed to the sharpening of flint and other stone axe-blades on these sarsens. It is possible that these tools were sharpened for use in cutting and carving the timber levers and struts which would have been used in erecting the stones and constructing the tomb. Similar evidence for the sharpening of tools has been found at West Kennet Long Barrow, as well as later prehistoric monuments such as Stonehenge.
Coldrum Long Barrow is comparatively isolated from the other Medway Megaliths; in this it is unique, given that the other surviving examples are clustered into two groups. However, it is possible that another chambered tomb was located nearby; a razed, elongated earthen mound with an east-west orientation is located in a hollow at the foot of the downs just under a quarter of a mile to the north of the Coldrum Stones. It may be that this represents the remnants of another such monument which has had its stones removed or buried. Several large sarsens to the south of the Coldrums might represent the remnants of a further such tomb, since destroyed.
Ashbee suggested that given its size and comparisons with other long barrows, such as Fussell's Lodge, the Coldrum tomb could have housed the remains of over a hundred individuals. Excavations conducted in the early 20th century have led to the methodical discovery and removal of what was believed to be the remains of twenty-two human individuals. These remains were examined by Sir Arthur Keith, the conservator of the museum at the Royal College of Surgeons. He published his results in 1913, in a paper largely concerned with discerning racial characteristics of the bodies.
A subsequent re-analysis of the bones was conducted in the early 21st century, and published in the Proceedings of the Prehistoric Society in 2013: the project presented "osteological analysis, Bayesian modelling of radiocarbon dates, and carbon and nitrogen stable isotope analysis to inform on the demography, burial practices, diet and subsistence, and chronology of the Coldrum population". Disputing earlier conclusions, it stated that the minimum number of individuals was seventeen. These were then further identified as probably belonging to nine adults (probably five males and four females), two sub-adults, four older children, and two younger children (one around five years old, the other between 24 and 30 months old).
Keith had suggested that the crania he examined displayed similar features, which he attributed to the different individuals belonging to "one family - or several families united by common descent." Similar observations had been made regarding the crania from other long barrows in Britain, although osteoarchaeologists Martin Smith and Megan Brickley noted that this was not necessarily representative of a family group. Instead, they stated that it would also be consistent with "a population that was still relatively small and scattered", in which most individuals were interrelated.
Wysocki's team noted that in all but one case, the fracture morphologies are consistent with dry-bone breakage. Three of the skulls exhibited evidence that they had experienced violence; a probable adult female had an unhealed injury on the left frontal, while an adult of indeterminate sex had an unhealed fracture on the left frontal, and a second adult female had a healed depressed fracture on the right frontal.
Isotope analysis of the remains revealed δ13C values that were typical of those found at many other Southern British Neolithic sites, albeit with significantly higher values of δ15C, which grew over time. Although this data is difficult to interpret, it was identified as probably reflecting a terrestrial diet high in animal protein that over time was increasingly supplemented with freshwater river or estuarine foods. In the case of the older individuals whose remains were interned in the tomb, the tooth enamel was worn away and the dentine had become exposed on the chewing area of the crowns.
Radiocarbon dating of the remains suggested Early Neolithic activity began at the site during 3980–3800 calibrated BCE (95% probability) or 3960–3880 cal BCE (68% probability), when the first human remains were buried at the site. It then suggested that after an interval of either 60–350 years (95% probability) or 140–290 years (68% probability), further depositions of human remains were made inside the tomb. This second phase probably began in 3730–3540 cal BCE (95% probability) or 3670–3560 cal BCE (68% probability). The radiocarbon dating of the human remains does not provide a date for the construction of Coldrum Long Barrow itself; it is possible that the individuals died either some time before or after the monument's construction.
Cut-marks were identified on a number of the bones (two femora, two innominates, and one cranium), with osteoarchaeological specialists suggesting that these had been created post-mortem as the bodies were dismembered and the bones removed from their attached ligaments. However, they further suggested that the lack of such cut-marks on certain bones was suggestive that the body had already undergone partial decomposition or the removal of soft tissues prior to the process of dismemberment. The precision of the cut-marks suggests that this dismemberment was done carefully; "they do not suggest frenzied hacking or mutilation." None of the criteria that osteoarchaeologists deem diagnostic of cannibalism were found on the bones.
This cut-marked human bone assemblage represented the largest yet identified from within a Neolithic long barrow in Southern Britain, although similar evidence for dismemberment has been found from a number of other Neolithic British sites, such as West Trump, Eyford, Aldestrop, and Haddenham. There are two possibilities for how this material developed. The first is that the bodies of the dead were excarnated or exposed to the elements, followed by a secondary burial within the tomb. The second is that they were placed in the tomb, where the flesh decomposed, before the bodies were then rearranged within the tomb itself. These practices may have been accompanied by necrophagy, shamanism, or magical practices, direct evidence for which does not survive.
The inclusion of occupational debris over the bones was not unique to the site but common in chambered tombs from southern England. On the basis of an example discovered at Kit's Coty House, Ashbee thought it apparent that the contents of the Coldrum's chamber would have been compartmentalised by medial slabs, which served the same purpose as the side chambers of West Kennet and Wayland's Smithy.
Damage and dilapidation
All of the surviving megalithic tombs from the Early Neolithic period have suffered from neglect and the ravages of agriculture. Although archaeologist Paul Ashbee noted that the Coldrum Stones represent "Kent's least damaged megalithic long barrow", it too has suffered considerable damage, having become dilapidated and fallen apart over the six millennia since its original construction. Most prominently, the eastern side has largely collapsed, with the stones that once helped to hold up the side of the barrow having fallen to the bottom of the slope. Conversely, it is possible that the sarsens at the bottom of the slope were not part of the original monument, but were stones found in nearby fields which were deposited there by farmers.
Excavation of Chestnuts Long Barrow revealed that it had been systematically destroyed in one event, and Ashbee suggested that the same may have happened to the Coldrum Stones. He believed that the kerb-stones around the barrow were toppled, laid prostrate in the surrounding ditch, and then buried during the late thirteenth or early fourteenth century, by Christians seeking to obliterate non-Christian monuments. He suggested that in subsequent centuries, locals raided the damaged tomb for loamy chalk and stone, which was then re-used as building material.
Folklore and folk tradition
In a 1946 paper published in the Folklore journal, John H. Evans recorded the existence of a local folk belief that a battle was fought at the site of the Coldrum Stones, and that a "Black Prince" was buried within its chamber. He suggested that the tales of battles taking place at this site and at other Medway Megaliths had not developed independently among the local population but had "percolated down from the theories of antiquaries" who believed that the Early Medieval Battle of Aylesford, which was recorded in the Anglo-Saxon Chronicle, took place in the area.
Evans also recorded that there was a folk belief in the area that applied to all of the Medway megaliths and which had been widespread "up to the last generation"; this was that it was impossible for any human being to successfully count the number of stones in the monuments. This "countless stones" motif is not unique to this particular site, and can be found at various other megalithic monuments in Britain. The earliest textual evidence for it is found in an early sixteenth-century document, where it applies to the stone circle of Stonehenge in Wiltshire, although in an early seventeenth-century document it was being applied to The Hurlers, a set of three stone circles in Cornwall. Later records reveal that it had gained widespread distribution in England, as well as a single occurrence each in Wales and Ireland. The folklorist S. P. Menefee suggested that it could be attributed to an animistic understanding that these megaliths had lives of their own.
In recent years,[when?] a tradition has developed in which the Hartley Morris Men, a morris dancing side, travel to the site at dawn every May Day in order to "sing up the sun". This consists of a number of dances performed within the stones on top of the barrow, followed by a song performed at the base of the monument.
Antiquarian and archaeological investigation
Early antiquarian descriptions
The earliest antiquarian accounts of Coldrum Long Barrow were never published. There are claims that at the start of the nineteenth century, the Reverence Mark Noble, Rector of Barming, prepared a plan of the site for Gentleman's Magazine, although no copies have been produced to verify this. Between 1842 and 1844, Reverend Beale Post authored Druidical Remains at Coldrum, in which he described the monument; it remained unpublished at the time, however. Associating the site with the Iron Age druids, Post's suggestion was that the name "Coldrum" derived from the linguistically Celtic "Gael-Dun", and that the chiefs of some of the Belgic Gauls were interned there. He further reported that in both 1804 and 1825, skulls had been found at the site. In 1844, an antiquarian known as Thomas Wright published a note on the Coldrum Stones and other Medway Megaliths in The Archaeological Journal. They had been alerted to their existence by a local vicar, Reverend Lambert B. Larking, and proceeded to visit them with him. Describing the Coldrums, Wright mentioned "a smaller circle of stones" to the others in the area, with "a subterranean cromlech in the middle". They further added that "it is a tradition of the peasantry that a continuous line of stones ran from Coldrum direct to the well-known monument called Kit's Cotty [sic] House", attributing this to the variety of megaliths which were scattered throughout the landscape.
In 1857, the antiquarian J.M. Kemble excavated at the site with the help of the Rev. Larking, providing a report of their findings to the Central Committee of the British Archaeological Association. Describing the monument as a stone circle, they asserted that they discovered Anglo-Saxon pottery at the site, and noted that as well as being called the Coldrum Stones, the monument also had the name of the Adscombe Stones, which Kemble believed originated with the Old English word for funeral pile, ad. In August 1863, the Archaeological Institute, who were then holding their week-long meeting in Rochester, took a tour to visit the site, guided by the antiquary Charles Roach Smith. That year, the monument was described in a copy of Gentleman's Magazine by Yorkshire antiquary Charles Moore Jessop, who believed it to be a "Celtic" stone circle.
In 1869, the antiquarian A.L. Lewis first visited the site, and was informed by locals that several years previously a skull had been uncovered from inside or near to the chamber, but that they believed it to be that of a gypsy. A later account elaborated on this, stating that two individuals excavated in the centre of the dolmen without permission, discovering a human skeleton, the skull of which was then re-buried in the churchyard at Meopham. In an 1878 note published in The Journal of the Anthropological Institute of Great Britain and Ireland, Lewis noted that while many tourists visited Kit's Coty House, "very few goes to or ever hears of a yet more curious collection of stones at Colderham or Coldrum Lodge". He believed that the monument consisted of both a "chamber" and an "oval" of stones, suggesting that they were "two distinct erections". In 1880, the archaeologist Flinders Petrie listed the existence of the stones at "Coldreham" in his list of Kentish earthworks; although noting that a previous commentator had described the stones as being in the shape of an oval, he instead described them as forming "a rectilinear enclosure" around the chamber. He then included a small, basic plan of the monument.
In August 1889, two amateur archaeologists, George Payne and A.A. Arnold, came across the monument, which they noted was known among locals as the "Coldrum Stones" and "Druid Temple"; according to Payne, "the huge stones were so overgrown with brambles and brushwood that they could not be discerned". He returned the next year, noting that at this point, the brushwood had been cut away to reveal the megaliths. In his 1893 book Collectanea Cantiana, Payne noted that although it had first been described in print in 1844, "since that time no one seems to have taken the trouble to properly record them or make a plan", an unusual claim given that a copy of Petrie's published plan existed in his library. For this reason, after gaining permission from the landowner, he convinced Major A.O. Green, Instructor in Survey at Brompton, to conduct a survey of the monument in August 1892. He also wrote to Augustus Pitt-Rivers, encouraging him to schedule the Coldrum Stones under the Ancient Monuments Act. Payne described the Coldrum Stones as "the finest monument of its class in the county, and one worthy of every care and attention." Comparing it to other monuments of its type in Britain, he asserted that it was undoubtedly "of sepulchral origin, belonging to a period anterior to the Roman domination of Britain." Payne also noted a folk tradition that there were stone avenues connecting Coldrum to the Addington Long Barrow, although asserted that he was unable to discover any evidence for the existence of this feature.
In 1904, George Clinch published a note on the Medway Megaliths in the Royal Anthropological Institute's journal, Man, in which he referred to the Coldrum Stones as "at once the most remarkable and the least known of the whole series." Suggesting that its design indicates that it was built during "a late date in the neolithic age", he compared the workmanship in producing the megaliths to that at the stone circle of Stonehenge in Wiltshire, although noted that they differed in that the Coldrum Stones clearly represented "a sepulchral pile". Ultimately, he ended his note by urging for the site to be protected under the Ancient Monuments Protection Act. In that same issue, Lewis included an added note in which he rejected the idea that the monument had once been covered by an earthen tumulus because he could see "no evidence that anything of that kind ever existed", and instead he interpreted the site as a stone circle, comparing it to the examples at Avebury, Arborlow, and Stanton Drew, suggesting that the central chamber was a shrine.
The Coldrum Stones have been excavated on multiple occasions. On 16 April 1910, the amateur archaeologist F.J. Bennett began excavation at the site, after previously having uncovered some Neolithic lithics from Addington Long Barrow. He soon discovered human bones "under only a few inches of chalky soil". He returned to the site for further excavation in August 1910, this time with his niece and her husband, both of whom were dentists with an interest in craniology; on that day they discovered pieces of a human skull, which they were able to largely reconstruct. A few days later he returned to excavate on the north-west corner of the dolmen with the architect Mr E.W. Filkins; that day, they found a second skull, further bones, a flint tool, and pieces of pottery.
Later that month, George Payne and F.W. Reader met with Bennett to discuss his finds. With the aid of two other interested amateur archaeologists, Mr Boyd and Miss Harker, both from Malling, excavation resumed in early September. In 2009, the archaeologists Martin Smith and Megan Brickley asserted that Bennett's excavations had taken heed of the advice of Pitt-Rivers that excavations should be recorded in full. They noted that Bennett had provided "clear plan and section drawings, photographs of the monument and careful attempts to consider site formation processes." Suggesting that the monument was constructed on agricultural land, in his published report Bennett cited the ideas of anthropologist James Frazer in The Golden Bough to suggest that the Coldrum Stones "monument may at one time have been dedicated, though not necessarily initially so, to the worship of the corn god and of agriculture." He proceeded to theorise that the human remains found at the site were the victims of human sacrifice killed in fertility rites. However, Evans would later state that "we have no means of knowing" whether human sacrifice had taken place at the site.
In September 1922, Filkins once again began excavating at the site, this time with the aid of a resident of Gravesend, Charles Gilbert. Their project was financed through grants provided by the British Association and the Society of Antiquaries, with Filkins noting that at the time of its commencement, "a miniature jungle" had grown up around the site which had to be cleared. Excavation continued sporadically until at least 1926. Human remains were discovered, and placed into the possession of Sir Arthur Keith of the Royal College of Surgeons. This excavation revealed all the existing sarsens surrounding the monument, a number of which had previously been buried beneath earth. The stones of the dolmen were shored up with concrete foundations where Filkins deemed it necessary. Although Filkins' excavation was comprehensive, it did ignore stone holes, packing stones, and their relationship to the mound. In 1998, Ashbee noted that while from "a present-day perspective, it is possible to see shortcomings[...] in terms of the general standards of the early part of this century, there is much to commend."
In his 1924 publication dealing with Kent, the archaeologist O. G. S. Crawford, then working as the archaeological officer for the Ordnance Survey, listed the Coldrum Stones alongside the other Medway Megaliths.

In 1926, the Coldrum Stones were given to The National Trust, who dedicated it as a memorial to Kentish historian Benjamin Harrison. A plaque was erected to mark this, which erroneously termed the monument a stone circle. Owned by heritage charity The National Trust, the site is open to visitors all year round, free of charge. On their website, the Trust advises visitors to look for "stunning views from the top of the barrow". John H. Evans characterised the site as "the most impressive" of the Medway Megaliths.
