This one in Curraghroche, County Limerick, offers nothing of the sort. What exists here, or rather what may exist, is a faint sub-circular shape visible only from the air, picked out briefly in the geometry of a crop growing above it. On the ground, there is simply reclaimed pasture, with no surface feature to suggest anything lies beneath.

The site came to light not through excavation or historical research but through an unlikely bureaucratic process: the aerial photography carried out in connection with the Bórd Gáis Éireann Curraleigh West-Limerick gas pipeline survey. On photographs taken on 11 September 1982, a cropmark, that is, a variation in plant growth caused by buried features affecting soil moisture and depth, appears in a roughly circular form. Cropmarks of this shape are often associated with enclosures of prehistoric or early medieval date, though without excavation it is impossible to say more. Notably, the feature does not appear on any historic Ordnance Survey Ireland maps, suggesting it was either overlooked, already too degraded to register, or simply lying low beneath centuries of agricultural activity. By the time satellite imagery was captured between 2011 and 2013, and in subsequent Google Earth orthoimages, no trace was visible at all. The record was compiled by Fiona Rooney and uploaded in October 2021.

For anyone curious enough to seek it out, the site lies in reclaimed pasture approximately 60 metres south of the townland boundary with Deerpark. There is, practically speaking, nothing to see on the ground, and that is rather the point. What makes this place worth knowing about is precisely its elusiveness: a feature legible for one moment in 1982, caught by a camera attached to a gas company survey, and since returned entirely to invisibility. The most useful thing a visitor can bring is the original aerial photograph, which remains the only document in which this possible earthwork has ever been clearly present.
