It measures approximately seven metres across, and what defines it is not a mound but a fosse, a ditch, the kind that would once have enclosed a burial monument of the prehistoric period. The feature is subtle enough that it escaped formal notice until aerial and satellite photography caught it from above, where cropmarks and soil differences invisible at ground level become suddenly legible.

The site belongs to a category known as a ditch barrow, a funerary monument typically consisting of a circular enclosure defined by a surrounding ditch rather than, or sometimes in addition to, a raised earthen mound at its centre. Such monuments were constructed across Ireland and Britain during the Bronze Age, though precise dating for any individual example requires excavation. This particular site in Dromeenboy was identified by archaeologist Caimin O'Brien, whose record was uploaded in June 2020. Its visibility depends almost entirely on remote sensing data, specifically Digital Globe orthophotos taken between 2011 and 2013, as well as earlier Ordnance Survey Ireland aerial photographs, both of which showed the circular fosse as a cropmark against the surrounding reclaimed pasture. The process of land reclamation, which involved draining and levelling boggy or marginal ground for agricultural use, has obscured the monument at the surface while paradoxically preserving enough subsurface trace for aerial survey to detect it.

There is nothing to see at ground level in the conventional sense. The field gives no obvious indication of what lies beneath, and the site is on private agricultural land, so any visit would require permission from the landowner. For those with a serious interest in the archaeology of the region, the record sits within the National Monuments Service database, where the orthophotographic evidence can be examined directly. The site serves as a quiet reminder of how much of Ireland's prehistoric landscape has been absorbed into the working countryside, surviving not as a visible earthwork but as a faint signal in the soil, only readable when viewed from altitude and in the right conditions of light and growth.
