Nothing about it announces itself, and no original entrance survives to suggest how it was ever meant to be approached. That combination of deliberate shaping and apparent inaccessibility is precisely the point: this is not a fortification or a settlement in the ordinary sense, but a piece of designed landscape, a feature created to be seen rather than entered, most likely from the windows or grounds of a nearby country house.

The feature measures roughly 40 metres north to south and 38 metres east to west, and its history can be traced through two Ordnance Survey snapshots. On the six-inch map of 1837, it appears as a tree-covered irregular enclosure sitting at the junction of several field boundaries. By the time the twenty-five-inch survey was carried out in 1911, it had resolved into a more clearly circular, tree-covered form. Tree-rings of this kind were a common ornamental device in eighteenth and nineteenth-century estate landscapes across Ireland and Britain, planted on prominent ground to create a visual focal point in an otherwise open countryside. The bank and accompanying fosse, a shallow outer ditch, have been heavily modified over time and absorbed into the working field boundary, which partly explains why the feature reads today as agricultural rather than aesthetic. Within the enclosure, the remains of a subrectangular structure survive at the western inner face of the bank, and a house site was recorded at the northern inner face as recently as 1976, suggesting the hillock had accumulated earlier or informal occupation before or alongside its ornamental use. The most plausible explanation for the whole ensemble is that it was laid out in connection with Richmount Hill house, which stands approximately 320 metres to the south-east, and a related landscape feature lies around 220 metres to the south-south-west, hinting that the two formed part of a broader scheme of estate improvement.
