It cannot be seen from the ground at all. The only reason anyone knows it is there is because of what cereal crops do when their roots hit disturbed subsoil: they grow differently, and from the air, those differences show up as faint lines of contrasting colour. Two wide fosses, the term for the ditches that typically define or defend an enclosed area, appear on aerial photographs as cropmarks, tracing what appears to be two sides of a rectangular enclosure roughly 45 metres along its north-west to south-east axis and around 30 metres across.

What makes this site quietly puzzling is the absence of the other two sides. The slope is described as having good conditions for the preservation of archaeological features, which means the missing walls or ditches are unlikely to have simply eroded away. Whether they were never built, were constructed differently and left no comparable trace, or lie just beyond the surveyed area is unclear. Rectangular enclosures of this kind in Ireland can date from any number of periods, and without excavation there is little to say with confidence about who made this one or why. What can be said is that the two fosses that do survive suggest deliberate, structured construction on a meaningful scale.

Because the site is entirely invisible at ground level, there is nothing to observe on a visit in any conventional sense. Its existence is, for now, an aerial fact rather than a landscape one.
