This is not a prehistoric fort or a natural accident of planting; it is a designed landscape feature, the kind of deliberate arboreal gesture that landowners across Ireland and Britain made during the eighteenth and nineteenth centuries to ornament their estates, signal ownership, and impose a sense of order on the countryside. Tree-rings of this type were sometimes planted purely for visual effect, a wooded punctuation mark on the skyline, and that seems to be precisely the function this one was intended to serve.

The earthen bank that follows the hillock's contours measures roughly two metres wide, rising about 1.2 metres on its outer south-western face, with the enclosed area inside spanning somewhere between fifty and fifty-five metres across. The feature does not appear on the Ordnance Survey six-inch map of 1838, which suggests it had not yet been planted by that date; by the 1916 edition, however, it is recorded as a wooded subcircular enclosure. That window places its creation firmly in the Victorian era, a period when such ornamental planting was fashionable across landed estates. Three quarry pits, each between ten and fifteen metres across, cut into the northern, eastern, and southern slopes of the hillock, hinting that the material for the enclosing bank may have been dug from the hillside itself during construction. The interior today is grassy and somewhat overgrown, with brambles, hawthorn, and a few ash trees filling the space that was once presumably kept clear to take in the views the elevated position commands.
