No headstones survive, and at ground level the outline of the enclosure is not visible at all. The site is known only because it was named and mapped, specifically recorded as a children's burial ground on the Ordnance Survey six-inch map of 1840, with dimensions of roughly fifteen metres north-west to south-east and ten metres north-east to south-west.

Places like this are sometimes called cillíní, informal burial grounds used historically for unbaptised infants and others who, under Catholic practice, could not be interred in consecrated ground. They were often situated at the margins, physically and socially, on old boundaries, in rough or uncultivated land, away from the main parish cemetery. The Carrowgar site fits that pattern, occupying ground that remains rough pasture today. A possible outline has been detected in aerial photography, but that faint trace in the imagery corresponds to nothing a person standing in the field could identify. The location on current maps is derived from the first edition Ordnance Survey, laid over modern mapping, making the 1840 record the primary evidence that this place ever existed in any formal sense.
