No earthwork rises from the field, no ditch catches the eye, no stonework breaks the grass. The only evidence that something was once built here comes from the air, where subtle differences in crop growth betray the outline of a structure that has otherwise entirely vanished into the soil beneath.

The enclosure is known from a cropmark, the phenomenon whereby buried ditches or walls cause crops growing above them to ripen at slightly different rates, producing faint discolourations legible only from altitude, and only at certain times of year. The mark recorded here reveals a univallate enclosure, meaning one defined by a single boundary ditch or bank, roughly circular and approximately 27 metres in diameter. Enclosures of this kind are among the most common archaeological features in the Irish landscape, most often associated with early medieval settlement, though without excavation the date and function of any individual example remains uncertain. This one was identified through aerial photography rather than fieldwork, and so far as the available record goes, the ground itself has never been opened to investigate what lies beneath.
