No ridge, no earthwork, no line of stones betrays it to anyone walking the pasture. Its existence is known only from a single aerial photograph taken in 1989, in which the ghost of a linear bank appears as a cropmark, a phenomenon where buried or subsurface features cause subtle differences in vegetation growth above them, making the outlines of otherwise invisible structures legible from the air.

The cropmark traces a bank running approximately fifty metres in length, radiating outward from the north-western arc of a nearby rath, the circular earthwork enclosure type that was a common form of defended farmstead in early medieval Ireland. The relationship between the two features is suggestive. Field boundaries associated with raths were a functional part of the wider agricultural landscape surrounding such enclosures, dividing and managing grazing land, and a bank extending from the outer edge of a rath would have served to demarcate the fields belonging to whoever occupied it. Whether this particular bank is genuinely contemporary with the rath, or represents a later reuse of the same ground, cannot be determined from aerial evidence alone.

What makes the site quietly compelling is precisely its invisibility. The photograph that revealed it, taken as part of an oblique aerial programme in 1989, captures a moment of legibility that the landscape does not otherwise offer. Standing on that slope today, there would be nothing to see.
