No cartographer recorded it on the Ordnance Survey's historic mapping. No earthwork survives to suggest a mound or ditch. The site is, in every practical sense, invisible, and yet the ground remembers it, or at least it did once.

A ring barrow is a burial monument of prehistoric origin, typically consisting of a low circular mound surrounded by a ditch and sometimes an outer bank. They are found across Ireland and Britain and are generally associated with the Bronze Age, though some date earlier or later. The example at Dromeenboy was identified not by field survey but by cropmark, the phenomenon whereby buried features, including ditches or banks long since levelled, affect the growth of overlying vegetation in ways that become legible from altitude. During the Bruff aerial photographic survey of 1986, a circular-shaped cropmark was recorded at this location, catalogued as Bruff 144, AP 4/3730. The monument sits on the floodplain of the Dead River, which runs approximately 45 metres to the north, near that river's confluence with the Mulkear, some 155 metres to the northwest. Floodplain soils are periodically waterlogged and then dry out, conditions that can make buried features more visible as cropmarks during dry spells. By the time Digital Globe orthophotos were taken between 2011 and 2013, and again when a Google Earth image was captured on 28 June 2018, nothing was visible at all.

There is no monument to seek out here in any conventional sense. The land is reclaimed pasture, flat and unremarkable to the eye, with the Dead River close by to the north. For anyone curious enough to visit, the most honest experience on offer is the landscape itself: the low-lying floodplain, the proximity of two converging rivers, and the knowledge that whoever chose this spot for burial in prehistory understood something about this confluence that has otherwise been entirely forgotten. The aerial survey image remains the primary record, and the site is best appreciated through that photograph rather than any feature on the ground.
