It is, in all likelihood, nothing of the sort. The feature is now understood to be a tree-ring, a deliberate planting enclosure of post-1700 date, part of the designed landscape belonging to a nearby house that appears on the 1837 Ordnance Survey map under the name Sea View.

Tree-rings are ornamental or functional circular earthworks, edged with a low bank and sometimes a ditch, within which trees were planted in a formal arrangement, often as a feature of the grounds of a Georgian or later country house. This example measures roughly 12 metres across and is enclosed by an earthen bank about 1.4 metres wide. The bank is slight, rising only around 10 centimetres on the interior and 40 centimetres on the exterior, and the outer ditch has all but vanished at ground level, surviving now only as a crop mark visible under the right conditions. It is one of five such circular features that appear in close proximity on the 1913 edition of the six-inch Ordnance Survey map, all of them in the field immediately north of Sea View, through which the laneway to the house still runs. The 1837 map shows no trace of these circular forms, but does record trees in the same field, suggesting the planting was already established by then, even if the earthworks had not yet been formally surveyed or were too subtle to warrant marking.

The misclassification as a barrow is a reminder of how easily the traces of designed landscapes can be mistaken for something far older. The geometry is similar, the scale is comparable, and without documentary context, a low circular bank with a ditch reads much the same whether it was raised in the Bronze Age or laid out by a landlord improving his grounds two centuries ago.
