In a field of pastureland east of Mountseskin House in County Dublin, a small oval mound once rose roughly two and a half metres from the ground, measuring about ten metres in length and just under seven in width. It was the kind of modest earthwork that would have gone largely unremarked by a passing walker, yet it was old enough to warrant formal attention. Now it is gone entirely, levelled to the point where even the grass gives nothing away.

The mound was surveyed by the Archaeological Society of University College Dublin in 1942, one of many such field investigations carried out during a period of renewed interest in Ireland's prehistoric earthworks. What the survey concluded about its origins or function is not fully recorded here, but the structure belonged to a wider prehistoric landscape. To the west lie two ring-barrows, a type of low circular burial monument typically defined by a central mound or flat area enclosed within a ditch and outer bank, and these survive where their neighbour did not. At some point after 1942, the mound was removed, a fate documented by Healy in 1975. Whether it was cleared for agricultural convenience or simply lost to gradual land improvement is not recorded, but the result is the same: an absence where an ancient feature once stood.

The site sits in open farmland that slopes away to the southeast of Mountseskin House, and there is no publicly marked access or visitor infrastructure of any kind. The two surviving ring-barrows to the west are recorded in the Sites and Monuments Record and offer at least some visible trace of the prehistoric activity that once defined this corner of south County Dublin. For anyone with a particular interest in the archaeology of the Dublin upland fringe, the area repays careful attention on the map even when the ground itself stays silent.
