This particular rath, a type of circular earthwork enclosure used in early medieval Ireland typically as a farmstead or place of security, has left no surface trace whatsoever. It cannot be visited in any conventional sense, and yet it was evidently real enough to be mapped, recorded, and eventually photographed from the air.

The enclosure appears on the Ordnance Survey maps produced between 1841 and 1842, and again on the revised edition of 1916, which suggests it was at least partially visible to nineteenth and early twentieth-century surveyors. By 1974, when the Geological Survey of Ireland conducted aerial photography of the area, the earthworks themselves were gone, but the site revealed itself as a crop mark, a phenomenon where buried features influence the growth of plants above them, producing subtle variations in colour and height that are invisible from the ground but legible from altitude. C. Toal's North Kerry Archaeological Survey, published in 1995, places the site to the south-east of another recorded monument and documents it under the reference number 570. Between the mapping of the 1840s and the aerial photography of the 1970s, the physical structure had been entirely levelled, leaving the land looking like any other field in Granshagh.

What the crop mark confirms is that the underlying archaeology has not simply vanished but is compressed into the earth, the filled-in ditches and disturbed subsoil still shaping what grows above. The site is a useful reminder that absence of visible remains does not mean absence of history, only that the evidence has shifted into registers that require different tools to read.
