The 1842 Ordnance Survey six-inch map marks the spot as a roughly circular area about twelve metres across and labels it, in the old English lettering reserved for ancient sites, as "Site of Knockaunabulloge." That cartographic distinction is itself a small curiosity: by the time the surveyors came through, the place was already being recorded as a former something, a site of a thing rather than the thing itself.

The name Knockaunabulloge hints at the Irish landscape-naming tradition that attached specific, often descriptive terms to even modest features of the ground. The enclosure, a broadly circular boundary feature of the kind common across early medieval Ireland, was typically formed by an earthen bank or fosse and might have enclosed a farmstead, an animal pen, or a more ritually significant space. Here, what survives is an arc of low raised ground running from the south-west around to the north-west, the last legible fragment of what was once a complete circuit. Enclosures of this type, sometimes called ringforts or raths, are among the most numerous surviving field monuments in Ireland, yet many, like this one, have been reduced by centuries of ploughing, grazing, and the general settling of earthworks back into the land.
