Sitting in gently undulating wet pasture, it registers on an aerial photograph as a roughly circular crop or soil mark, approximately ten metres in diameter, its outline having been entirely overlooked by the Ordnance Survey cartographers who mapped Ireland at six-inch scale across successive editions. Whatever they walked past, they did not record it. Standing on the ground today, there is nothing to see at all.

A barrow is a burial mound, typically of prehistoric date, though the term covers a range of earthen funerary monuments. This one has left so slight an impression on the land that it does not rise visibly above the surrounding field surface, surviving only as a ghostly trace legible to aerial survey. About two hundred metres to the west lies a separate embanked enclosure, a roughly defined area bounded by an earthen bank, suggesting this part of Ballynacree may have accumulated significance over time, with more than one monument occupying the same quiet stretch of pasture.
