A circular cropmark roughly 35 metres in diameter, defined by a buried ditch, becomes legible only from the air, where differences in soil moisture and plant growth betray the outline of a structure that has otherwise been swallowed entirely by centuries of agricultural levelling. Cropmarks form when crops or grasses above a buried feature grow differently from surrounding vegetation, taller and greener over a ditch that retains moisture, or shorter and paler over compacted ground. Here, the circle is the thing, and the circle suggests something deliberately made.

The earthwork was identified from aerial imagery rather than any ground-level survey. A Google Earth orthoimage captured on 24 March 2017 shows the circular ditch clearly enough to record it, while an earlier Digital Globe orthophoto taken sometime between 2011 and 2013 preserves only a faint outline of the same form. The slight difference between the two images hints at how variable such features can be, dependent on season, rainfall, and the particular crop or grass cover at the time of capture. What the site actually was, whether a ringfort, a barrow, a prehistoric enclosure, or something else entirely, remains unconfirmed. Circular ditched enclosures are common across the Irish midlands and can span a wide range of periods and purposes, but without excavation, the function of this one stays open.
