No earthwork rises from the ground, no stones mark a perimeter, and no obvious feature catches the eye at field level. The site is known only because an aerial photograph, taken as part of the Cambridge University Collection of Aerial Photography, revealed a sub-rectangular cropmark pressed into the soil below. Cropmarks appear when buried archaeology affects how plants above them grow; ditches or pits retain moisture, encouraging lusher, taller growth, while compacted foundations starve roots and produce stunted, paler crops. Seen from the air in the right season and at the right angle, the outlines of otherwise invisible structures can become briefly legible.

What the photograph shows is a univallate enclosure, meaning one defined by a single ditch or bank, roughly 45 metres from north to south and around 40 metres from east to west. It is a scale consistent with the enclosed farmsteads that were common across Ireland from the early medieval period onward, though without excavation the date cannot be confirmed. One of the more telling details is a kink in a modern field boundary along the southern side, a small deviation that almost certainly preserves the line of the old enclosure beneath it. It is a pattern seen often in the Irish landscape, where hedgerows and fences were laid out along earlier earthworks simply because a slight rise or hollow in the ground made that the path of least resistance. The same aerial photograph also shows faint linear cropmarks elsewhere in the field, suggesting that further buried features may lie close by, their nature and relationship to the enclosure unclear.
