Three small circles lie buried beneath a field in Stephenstown, visible only from the air and only under the right conditions. They appear on a single aerial photograph as cropmarks, the ghostly outlines that appear in a dry summer when buried ditches or foundations cause the grass or grain above them to grow at a slightly different rate, betraying the shapes of long-vanished structures to anyone passing overhead at the right moment.

The three circular enclosures sit together on a low ridge in well-drained pasture, which is itself a detail worth noting. Low ridges in well-drained ground were favoured spots for early settlement in Ireland, offering a degree of elevation and dry footing without the exposure of a hilltop. Circular enclosures of this kind are common throughout the Irish landscape and are generally associated with early medieval ringforts, though without excavation it is impossible to say more about what stood here, when, or for how long. What the aerial photograph records, designated GSI N 337-6, is the faint geometry of three separate but closely associated features, each modest in scale. Nothing survives above ground.
