No earthwork rises from the soil, no ditch breaks the surface, no line of stones marks a boundary. The only evidence of its existence came from the air, when a 1970 aerial photograph revealed what specialists call a cropmark, a ghostly outline made visible when buried features beneath the soil cause crops above them to grow differently, typically taller and greener over filled-in ditches, or shorter and paler over compacted foundations. The shape that emerged was sub-rectilinear, meaning roughly rectangular but with softened or irregular corners, measuring approximately 70 metres along its northwest to southeast axis and around 20 metres across.

The site sits on the valley floor, just above the flood plain, a position that tells its own quiet story. Enclosures of this kind in Ireland range in date and function considerably; some are early medieval ringforts adapted to less circular ground plans, others are associated with settlement or agricultural activity stretching back into prehistory. Without excavation it is impossible to say what this particular enclosure once contained or who built it, and no such investigation appears to have taken place. What is known is that the surrounding landscape would have made it a reasonably sheltered and practical location, with open views across the valley and land that was presumably workable even in earlier centuries. The cropmark was identified from a Cambridge University Collection of Aerial Photography image, referenced as CUCAP BDL 32, taken in 1970.
