A D-shaped enclosure, roughly forty metres across its widest axis and about twenty-eight metres across its shorter span, reveals itself as a cropmark, the kind of subtle variation in vegetation colour and growth that betrays buried features beneath the soil. The enclosure is defined by a slight fosse, a shallow ditch, whose outline emerges when crops above it grow or ripen differently from those around them, a consequence of the disturbed and often moister ground that old ditches leave behind even after centuries of silting and ploughing.

The site came to notice through aerial imagery rather than any ground survey. Simon Dowling was the first to report it, identifying the cropmark on Google Earth in imagery dated July 2018. The shape is not entirely intact as it survives today: a later field bank running roughly west-northwest to east-southeast cuts across the southern part of the enclosure, itself accompanied by drainage ditches on either side, and this later intervention truncates the older feature. D-shaped enclosures of this kind are generally associated with early medieval settlement in Ireland, where a roughly circular or slightly flattened ring of earthwork would have enclosed a farmstead or small agricultural unit, though without excavation the date and function of this particular example remain a matter of inference rather than confirmed fact.
