At ground level, there is simply grass, gently rolling, giving no indication that anything lies beneath or within it. The site exists, in any practical sense, only from the air.

What aerial photography reveals is a faintly circular form, roughly twenty metres across, its outline poorly defined but suggestive of a former enclosure. Circular enclosures of this kind are a common feature of the Irish landscape; they range from prehistoric ringforts, which served as enclosed farmsteads, to early medieval ecclesiastical enclosures, and their traces survive in varying degrees of legibility. This one is at the far end of that spectrum. It does not appear on any edition of the six-inch Ordnance Survey map, which means it escaped the attention of nineteenth-century surveyors entirely, or had already been reduced to invisibility by the time they passed through. Whether it was ever recorded by eye on the ground, or whether aerial survey alone brought it into any kind of focus, is not clear. What is clear is that the pasture keeps its secret efficiently.
