It appears on the Ordnance Survey six-inch map from 1944 as a hachured ring, the standard cartographic shorthand for an earthwork whose edges slope or bank. Beyond that outline, it remains largely unknown, its physical presence swallowed by the afforestation that has spread across the area and made the site inaccessible.

Circular enclosures of this kind are a familiar if still imperfectly understood feature of the Irish landscape. Many are ringforts, the remains of enclosed farmsteads occupied from the early medieval period onwards, though some are older or served different purposes entirely. They typically consist of an earthen bank and outer ditch enclosing a domestic space, and they survive in their thousands across Ireland, sometimes as clear earthworks, sometimes as little more than a crop mark or a cartographic ghost. The Toormore example, with its modest diameter, fits broadly within that range, though without access to the ground, any firmer identification is speculation.
