Somewhere beneath the farmland of Levitstown in County Kildare, a vanished enclosure traces its outline in the soil, invisible to anyone walking the fields but legible, under the right conditions, from the air. The site survives only as a cropmark, a phenomenon that occurs when buried features such as ditches or walls affect the growth of crops above them, causing faint variations in colour or height that become readable in aerial photographs taken during dry summers. In this case, what the camera recorded was the ghost of a fosse, an enclosing ditch, curving around an irregular, polygonal area estimated at roughly fifty metres across at its widest point.

The evidence comes from an aerial photograph, reference CUCAP ASU 68, which captured not only the enclosure's outline but also the faint traces of what may be an associated field system nearby. The fosse defines a shape that is neither the neat circle typical of many ringforts nor a straightforward rectangle, but something more irregular, suggesting either an adaptation to local terrain or a less standardised form of enclosure than the canonical rural monuments of early medieval Ireland. Cropmarks of old field boundaries visible in the same photograph hint that this was once a working agricultural landscape, with the enclosure perhaps at its centre. The relationship between the enclosure and these field systems remains a matter of inference rather than excavation; no ground investigation appears to have been carried out, and so the site's date, function, and history remain open questions.
