No earthwork survives, no ditch, no raised bank. The only evidence that something once stood here emerged briefly on a single day in June 2010, when a specific combination of dry weather and growing crops made the buried outline of a roughly circular enclosure visible from the air as a cropmark. Cropmarks appear when buried features such as ditches or walls affect how crops grow above them: soil that fills an old ditch retains more moisture and produces taller, greener growth, while compacted foundations have the opposite effect. The result is a ghostly plan of whatever lies beneath, readable from altitude but invisible to anyone walking the field.

The enclosure measures approximately 32 to 34 metres in diameter, with a sub-rectangular annexe extending from its eastern side. This kind of enclosed settlement, a roughly circular area defined by a ditch and possibly a bank, is a form found widely across Ireland and associated broadly with the early medieval period, though without excavation it is impossible to date this particular example with any confidence. What little physical evidence has been recovered amounts to a single waste flint flake, found at the southern edge of the cropmark when the field was ploughed. A waste flake is a byproduct of flint knapping, the process of shaping flint tools, and its presence hints at prehistoric activity in the area, though a single stray piece is far too slender a thread from which to draw conclusions. The cropmark itself was not visible on any other aerial photographs examined, making that June 2010 image an unusually fortunate capture of something that has otherwise stayed completely hidden.
