This site in the townland of Spittle, County Limerick, sits in rough pasture just west of the boundary with the neighbouring townland of Ballynatona, and it owes its place in the archaeological record entirely to an accidental discovery made from the air, decades after any map-maker had cause to notice the ground.

The site came to light during examination of aerial photographs taken on 3 November 1984, as part of survey work carried out for a Bórd Gáis Éireann gas pipeline running between Curraleigh West and Limerick. The photographs, shot at a scale of 1:5,000 and catalogued under reference BGE 1/5000, 2606, revealed what appeared to be an earthwork complex beneath the pasture. Aerial photography of this kind works by catching subtle differences in how vegetation grows over disturbed or compacted soil, differences that are invisible at ground level but legible from above, particularly in certain lighting or seasonal conditions. No further detail about the nature or age of the earthworks is currently recorded, though a separate enclosed site, listed in the archaeological record as LI049-251, lies approximately 120 metres to the south, hinting that this corner of Limerick may hold more beneath its surface than the landscape suggests. Faint traces of the earthworks were later confirmed in Digital Globe orthoimages taken between 2011 and 2013, and are also visible on Google Earth.

Because the site lies in rough agricultural pasture and is not marked on any public map, there is no formal access point or waymarked path. The earthworks are most likely to be perceptible, if at all, through aerial or satellite imagery rather than on foot; the traces are described as faint even from above. Visitors with an interest in the area would do well to cross-reference the Google Earth orthoimages before attempting to locate anything on the ground, and should bear in mind that the land is private farmland. The neighbouring enclosure to the south, if accessible, may offer a more legible sense of the kind of archaeology present in this part of the county.
