A small circular enclosure was recorded on an estate map in 1811, and then, as far as the Ordnance Survey was concerned, it simply ceased to exist, absent from both the 1838 and 1920 six-inch sheets. What remains on the ground today is not quite what that earlier map described, which raises the quiet question of whether the two are even the same feature, or whether one was already fading from memory while the other quietly persisted in the soil.

The 1811 map was drawn up for Sir Robert Lynch-Blosse, a Connacht landowner whose estate boundaries and features were being formally documented in the manner typical of improving landlords of the period. The survival of that map in the National Library of Ireland (Ms. 2713) is what ties this otherwise anonymous earthwork to a named moment in time. What survives today is a subrectangular earthen platform, roughly 16.6 metres along its northwest to southeast axis and 9 metres across, defined by a low scarp, the kind of slight raised edge formed when ground is cut or built up and the surrounding slope gradually erodes away around it. The scarp reaches about 1.2 metres in height on the southwest side, though it has slumped considerably there and along the western end. When the site was inspected in 1998, its southeastern edge had been absorbed into a straight field fence, a common fate for earthworks in agricultural landscapes; that fence has since been removed. A shallow circular depression, roughly 3 metres across, sits at the eastern corner of the platform.
