This one, sitting in wet pasture in the townland of Spittle in County Limerick, barely announces itself at all. It never made it onto the Ordnance Survey's historic maps, and what survives is so faint that it took the analytical eye of an aerial photograph interpreter to confirm it existed in any meaningful sense.

The earthwork came to official attention not through a dedicated archaeological survey but as a byproduct of infrastructure. On 3 November 1984, aerial photographs were taken at a scale of 1:5000 as part of the Bórd Gáis Éireann pipeline project running from Curraleigh West to Limerick, and it was during the examination of those images, catalogue reference BGE 1/5000, 2608, that the feature was identified. The record was later compiled by Martin Fitzpatrick and uploaded to the national sites and monuments database in October 2021. That gap between discovery and formal documentation, nearly four decades, is itself a small reflection of how Ireland's archaeological record continues to be filled in gradually, often through sources that were never primarily archaeological at all. A barrow, a type of burial mound, lies roughly 170 metres to the northwest, recorded separately under the reference LI049-245, which raises the quiet possibility that this area held some significance in the prehistoric or early historic landscape, though the nature of the earthwork itself remains undefined in the record.

The site sits approximately 65 metres west of a local road, in ground that the notes describe as wet pasture, which is worth bearing in mind before visiting. That kind of terrain can make access difficult, particularly in the wetter months, and there is no guarantee of a clear view from the road. What trace exists is described as faint, detectable on Digital Globe orthoimages taken between 2011 and 2013 and on Google Earth imagery, but on the ground it may amount to very little that is visible to an untrained eye. The value here is less in what can be seen and more in what the record represents: a feature that survived long enough to be caught, almost accidentally, in the frame of a gas company's survey flight.
