This one in Curraghroche, County Limerick, does something quieter and in many ways more unsettling: it barely shows up at all. Lying in reclaimed pasture roughly sixty metres south of the townland boundary with Deerpark, the site does not appear on any historic Ordnance Survey Ireland maps. What evidence exists for it comes almost entirely from above, in the form of a cropmark, the faint discolouration that appears in growing crops or grass when buried features affect how plants draw moisture and nutrients from the soil. The shape that emerged from the ground here is sub-circular, suggesting the outline of an enclosure of some kind, though its age and precise function remain unconfirmed.

The site came to light not through a dedicated archaeological survey but as a byproduct of infrastructure work. Aerial photographs taken on 11 September 1982 for the Bórd Gáis Éireann Curraleigh West-Limerick gas pipeline corridor captured the cropmark on film, catalogued under reference BGE 1/10,560; 0121. Pipeline projects of that era routinely commissioned aerial photography along their proposed routes, and the resulting image archive has since proved valuable to researchers working on features that were never recorded by earlier mapping. Decades later, the same faint trace was still visible, appearing on a Digital Globe orthoimage taken between 2011 and 2013 and on Google Earth imagery from the same period. The record was formally compiled by Fiona Rooney and uploaded to the relevant heritage database in October 2021.

Because the earthwork is not visible as a surface feature in any obvious way, a visit to the area offers something closer to an exercise in looking carefully than in standing before a monument. The pasture setting means access depends entirely on landowner permission, and there is no established path or marker. The best chance of seeing anything meaningful at ground level would come during a dry summer, when cropmarks tend to reassert themselves in parched vegetation, though even then the effect is subtle. The site is perhaps most usefully appreciated through the archived aerial photographs themselves, which show how much of the Irish landscape carries traces of earlier occupation that only reveal themselves under particular conditions and from particular angles.
