It does not announce itself with earthworks you can walk around or masonry you can touch. What survives is a ghostly outline in the ground, a subcircular shape roughly 34 metres north to south and 28 metres east to west, defined by a single fosse. A fosse is simply a ditch, dug to demarcate and sometimes defend a bounded area, and here it traces a form that is characteristic of early enclosures found across Ireland, though no further details about its age or original function have yet been established.

The enclosure sits on fairly level ground, and it was first reported by Jean Charles Caillére. It appears only faintly in aerial imagery from the 2005 to 2012 MapGenie dataset, the kind of trace that might easily be dismissed as a field boundary or a trick of light. By 2022, enhanced mapping made the outline considerably clearer. The fact that it took this long to be formally noted is itself part of what makes it interesting. Ireland's landscape holds a great many such features, submerged below the threshold of casual observation, waiting for the right combination of dry weather, low sun, and someone paying close attention.
