The ditch-barrow here is visible not as a mound, but as a circular outline pressed into the ground, defined by a fosse, which is essentially a surrounding ditch or trench dug to demarcate and enclose the burial area. It is the kind of monument that reveals itself most clearly not to the eye on the ground, but from above, appearing on aerial orthophotos as a ghostly ring in the grass.

What makes the Ballynagally site particularly interesting is the density of prehistoric funerary remains concentrated in this small area of countryside. The ditch-barrow sits within a broader landscape of related monuments: a cluster of three ring-ditches lies roughly 35 metres to the north-west, a second ditch-barrow appears 50 metres to the east, and another ring-ditch sits approximately 75 metres to the south-west. Ring-ditches are the surviving circular trenches that once surrounded burial mounds, the above-ground elements long since flattened by centuries of ploughing and farming. The Glenatrahaun Stream runs about 100 metres to the east. The record was compiled by Alison McQueen, Vera Rahilly, and Caimin O'Brien, and uploaded to the national monuments database in July 2020, with the monument's outline confirmed through Digital Globe imagery from 2011 to 2013 and Google Earth imagery from November 2018.

For anyone curious enough to seek this out, the setting is working farmland, so access would require landowner permission and a good deal of patience. The monument itself is not marked or interpreted on the ground, and without prior knowledge of what to look for, the circular fosse would be easy to miss. The best way to orient yourself before visiting is to consult the Ordnance Survey Ireland orthophotos or Google Earth, where the circular cropmark is discernible. Early summer or a dry spell following rain, when differential crop or grass growth picks out buried features, gives the best chance of seeing any surface trace. The broader cluster of monuments in the immediate vicinity suggests this part of Ballynagally was once a significant place for the communities who buried their dead here, though the land has long since been turned over to cattle and grass.
