The site, in the townland of Killeen close to its boundary with the neighbouring townland of Spittle, never made it onto the historic Ordnance Survey Ireland six-inch maps, which means it slipped past the great nineteenth-century documentation effort that catalogued so much of rural Ireland. What survives instead is a pattern of linear banks and circular cropmarks, the kind of subtlety that only becomes legible from the air.

The site came to light through an unlikely source. In November 1984, aerial photographs were taken during survey work for the Bórd Gáis Éireann Curraleigh West to Limerick gas pipeline, recorded at a scale of 1:5000 and catalogued as Site 3/40 on that project. Those photographs revealed what appears to be an earthwork complex, with linear features suggesting field boundaries and circular marks that may indicate the footprints of earlier structures. Cropmarks form when buried features, whether ditches, walls, or banks, affect how vegetation grows above them; in dry conditions or at certain times of year, the differential growth becomes visible from altitude even when nothing obvious shows at ground level. The Killeen site has remained detectable in more recent imagery too, appearing in Ordnance Survey Ireland orthoimages taken between 2011 and 2013, and on Google Earth. A separate earthwork, recorded separately as LI049-118, lies immediately to the west, hinting that this may be part of a broader archaeological landscape in the area.

For anyone curious enough to seek it out, the site lies in pasture on the western side of the Killeen and Spittle townland boundary in County Limerick. There is nothing to see at ground level in the conventional sense; this is a place best understood through the aerial and satellite images compiled as part of the record uploaded by Fiona Rooney in November 2021. Google Earth orthoimages offer the clearest view of the cropmark pattern, and comparing those against the historic six-inch Ordnance Survey maps, which show no trace of it, gives a sense of just how much archaeology lies unrecorded beneath ordinary farmland. If visiting the wider area, the field appears unremarkable from any roadside vantage, which is rather the point.
