The mound that stands at the center of Dane John Gardens today is visually arresting, rising some eighty feet above the surrounding ground and commanding views of the Cathedral and the city walls. Visitors tend to assume it is medieval, perhaps a Norman fortification, because Norman motte-and-bailey castles are the most familiar context in which conspicuous earthen mounds appear in English landscapes. The Normans did briefly adapt the mound for military use after the Conquest, but they did not build it. The best current evidence identifies it as part of a group of prehistoric or early historic earthworks considerably older than any Norman presence in Canterbury.
A Group of Mounds
The Dane John mound did not stand alone. Writing in 1875, T. G. Godfrey-Faussett, Fellow of the Society of Antiquaries, described the original configuration: a group of conical mounds, at least three confirmed and possibly more. The principal mound (which he labeled A) stood within the city walls at the position it still occupies. A second mound (B), smaller but similar in form, stood immediately outside the walls nearby. A third (C), closer in size to the Dane John mound itself and approximately equidistant, had stood nearby until its destruction a few years before Godfrey-Faussett wrote, when the construction of the Chatham and Dover Railway station removed it from the landscape. A fourth mound (D) was reported by tradition inside the walls near the cattle market, though the evidence for it was thin.
The three confirmed mounds had clearly belonged together. Their similar form, their spatial relationship, and their distribution relative to the Roman city walls all suggested a single origin. Crucially, Godfrey-Faussett argued that the line of the Roman wall on the southeastern side of the city had been drawn specifically to accommodate the position of the Dane John mound rather than cutting through it. If the wall deferred to the mound, the mound must predate the wall.
The Bronze Age Find
When the third mound was removed for the railway construction, antiquaries observed what emerged. Among the finds recovered from one of the companion mounds was a late Bronze Age socketed axe. Godfrey-Faussett considered this confirmatory of what the mounds’ situation had already suggested, arguing in his 1875 paper that the group was of Celtic or pre-Roman British origin, predating the Roman occupation of the site.
What the Evidence Currently Supports
The classification of the mounds has evolved since Godfrey-Faussett’s time. Historic England’s current descriptions of the site are more cautious. The Register of Parks and Gardens describes the Dane John mound as “surviving from a group of four Romano-British burial mounds of the 1st or 2nd century AD.” The Scheduled Monument entry (List Entry 1003780) notes that the mound “is thought to overlie a Roman burial mound and was built on an already existing mound dating to at least the Roman period.” Heritage Gateway describes a Roman barrow cemetery with “possible Bronze Age origins” suggested by the axe find.
The practical conclusion is that the mound cannot be precisely dated without targeted excavation. The Bronze Age socketed axe points toward earlier activity, possibly including prehistoric burial use. The mound’s incorporation within the Roman city walls, rather than being built over, is consistent with the mound being a pre-existing feature. The Romano-British barrow classification reflects the current archaeological consensus while leaving open the question of earlier phases. Godfrey-Faussett’s 1875 argument for Celtic or pre-Roman origin was not wrong to identify the mound as ancient; it simply could not draw on the fuller picture that later scholarship and the Heritage Gateway records provide.
Norman Use and Later History
The Normans briefly placed a timber motte-and-bailey castle on the mound’s summit after 1066, a use that appears to have ended by the early twelfth century when the stone Canterbury Castle was built to the northwest. After the abandonment of the motte, the mound returned to the condition it had occupied through the Saxon period: a prominent feature of the landscape without any particular current military use.
When Alderman James Simmons transformed the Dane John area into a public garden in 1790, he raised and reshaped the mound, adding approximately four metres to its height and creating the winding terrace walk that visitors still climb today. The mound that Simmons landscaped and the mound that Godfrey-Faussett argued over are the same feature, successive layers of use accumulating over what may be two millennia or more.
What is not in serious dispute is that the mound was present before the Norman castle phase and before the Romano-British city of Durovernum was built around it. Its earlier origins remain an open question that further archaeological work may one day resolve.
