What the surveyors captured in November 1984 was a circular cropmark, the kind of faint shadow in vegetation that betrays something buried beneath, suggesting a ditch-barrow of roughly five metres in diameter lying in the southern quadrant of a wider cluster of ancient monuments in Raheen, in the old barony of Coshlea.

A ditch-barrow is a burial mound, typically from the Bronze Age, defined and enclosed by a surrounding ditch rather than simply a raised earthen bank. The feature here was first identified on Bórd Gáis Éireann aerial photographs taken on 3 November 1984 as part of survey work for the Curraleigh West to Limerick gas pipeline (recorded as BGE 1/5000; 2580, Site 234). Cropmarks like this form when soil disturbed by ancient digging retains moisture differently from undisturbed ground around it, causing the grass or crops above to grow at a slightly different rate, a difference invisible at ground level but legible from the air. The same circular trace was subsequently confirmed on Digital Globe orthoimagery captured between 2011 and 2013, and again on a Google Earth image dated 18 November 2018, each time as a faint but consistent ring. It sits within a broader funerary landscape: another barrow lies just 19 metres to the west, and a cremation pit has been recorded approximately 60 metres to the south, suggesting this corner of Raheen was once a place of deliberate, repeated ritual significance.

The site today is unremarkable to the casual eye, sitting in ordinary pasture with no surface trace visible from the ground. There is no marker, no interpretation board, and nothing on the standard Ordnance Survey six-inch mapping to indicate its existence. The cropmark itself, when it appears at all, is best appreciated through the aerial and satellite images compiled by Fiona Rooney and uploaded to the national record in September 2021. If you are cross-referencing the national monuments database, the relevant record sits within the monument group LI049-033001/005, with this particular feature listed separately. Visiting the surrounding area in a dry summer, when soil moisture differences are most pronounced, offers the best theoretical conditions for any surface expression, though in practice the feature remains one best observed from above.
