It takes an aerial perspective to reveal the shape at all, and even then what emerges is irregular, resisting the tidy circular form associated with the more familiar ringforts scattered across the Irish midlands.

The enclosure was identified through aerial photography carried out by Leo Swan, whose work documenting cropmarks and earthworks from the air contributed significantly to the understanding of Irish archaeological landscapes. Cropmarks appear where buried features, walls, ditches, or filled pits, affect the growth of surface vegetation differently from the surrounding soil, making otherwise invisible outlines legible from above under the right conditions, usually during dry summers when stress in the crops reveals what lies beneath. The photograph, taken under reference LS_AS_35CT_00001_37, captures the outline of this particular enclosure in sufficient detail to confirm its presence, though the notes available say little more about its character, date, or function. Whether it was a settlement boundary, a stock enclosure, or something older remains an open question.
