It is barely knee-high at its tallest point, roughly four metres across, and traces an arc of about sixty metres from north-north-east to south. What it once enclosed, or whether it enclosed anything at all, is genuinely unknown.

What makes this earthwork quietly puzzling is not its modest dimensions but its cartographic silence. The Ordnance Survey's six-inch map of 1837, which recorded the Irish landscape in extraordinary detail during a period of intensive field survey, makes no mention of it. The feature appears only in the 1913 edition, marked there as a hachured angular arc, the kind of shading surveyors used to suggest a raised or banked form on the ground. By that point it was already a remnant, a levelled bank rather than anything upstanding. Whether it once formed part of a field boundary, the kind of earthen division that shaped agricultural land for centuries, or the outer edge of an enclosure, a bounded area perhaps associated with settlement or livestock management, remains unresolved. Its original extent is equally unclear; what survives may be only a fragment of something considerably larger.
