This one, sitting in wet pasture in Mitchelstowndown East, County Limerick, does none of that. It exists, as far as the archaeological record is concerned, primarily as a circular shadow in a field, captured on aerial photographs taken on a single November day in 1984 and not confirmed by anything visible on the ground since. It was never marked on the Ordnance Survey Ireland six-inch maps, which were the standard reference for landscape features through much of the nineteenth and twentieth centuries, meaning it slipped past generations of surveyors without notice.

The site came to light during survey work carried out ahead of the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline, when aerial photographs taken on 3 November 1984 revealed what appeared to be a cropmark, a circular outline produced when buried archaeology affects the growth of grass or crops above it, making the underlying shape legible from the air even when nothing survives at ground level. That photograph, catalogued as BGE 1/5000, reference 2779, Site 320, is the sole evidence for the barrow's existence. A barrow, broadly speaking, is a prehistoric burial mound, typically constructed of earth or stone, and ranging from modest humps in a field to substantial ceremonial structures. This particular site sits within a cluster of related monuments, with a separate earthwork recorded approximately fifteen metres to the north-west. When Digital Globe orthoimagery of the area was assessed between 2011 and 2013, and when Google Earth imagery was later examined, no surface trace of the barrow could be identified. The record was compiled by Fiona Rooney and uploaded to the national monuments database in September 2021.

Visitors arriving in the hope of seeing anything should manage their expectations carefully. The field is wet pasture, and depending on the season the ground will be soft underfoot. There is nothing to see at surface level, and the monument's presence is inferred rather than confirmed. What makes a visit worthwhile, if anything does, is the cluster of associated monuments in the immediate vicinity, which suggest this corner of east Limerick was once a place of some ritual or funerary significance. The cropmark, if the feature is ever revisited by aerial survey during a dry summer when soil moisture differentials are most pronounced, might yet yield a clearer outline. For now, the evidence lives in a single frame of aerial film taken four decades ago on a November morning.
