The enclosure measures roughly 172 metres in diameter, enclosing an area of about 2.37 hectares, which places it well beyond the scale of a typical ringfort. What makes it stranger still is how thoroughly it vanished from the record, surviving only in the field notes of one scholar before being levelled, then quietly rediscovered decades later through the close reading of aerial photographs.

The antiquarian Liam Price was the first to write it down, describing an outer ditch approximately 10 metres wide, an internal bank, and an inner ditch of around 6 metres across, the bank itself standing only a couple of feet high even then. That modest profile likely contributed to its eventual loss; a feature so low is easy to dismiss, plough through, or simply forget. Price's notes went largely unactioned, and the monument was subsequently levelled. It was not until 2016 that researcher O'Driscoll returned it to the record, identifying a circular vegetation mark on aerial photographs taken by Ordnance Survey Ireland around the year 2000, where a curvilinear cropmark traces the enclosure's arc from north to east. The eastern side of the enclosure follows the boundary between the townlands of Kilranelagh and Cloghnagaune, a detail that hints at how old such boundaries can be, sometimes preserving the ghost of a monument long after the monument itself has gone. Close by, in Cloghnagaune, stands St. Bridget's stone, suggesting this corner of the hill carried some significance across different periods. The site sits on the demesne lands associated with Kilranelagh House, which lies about 380 metres to the west-southwest.

On the ground today, the area is heavily overgrown and almost completely tree-covered, making any surface trace exceptionally hard to read. The enclosure exists more convincingly in aerial imagery than in anything a visitor might see underfoot, a reminder that some of the most substantial monuments in the Irish landscape are now perceptible only at a remove, their true shape belonging to the view from above rather than the walk across.
