This one in Curraghturk, County Limerick, does the opposite: it exists primarily as an absence. No surface feature marks it today, no ridge or hollow catches the eye, and it does not appear on any of the historic Ordnance Survey Ireland maps that recorded the Irish landscape in such careful detail across the nineteenth and twentieth centuries. What is known about it comes almost entirely from a single set of aerial photographs taken on the 3rd of November 1984, during survey work for the Bórd Gáis Éireann Curraleigh West-Limerick gas pipeline.

Aerial photography has long been one of archaeology's more unlikely tools. Differences in soil moisture and crop growth, invisible at ground level, can reveal the buried outlines of ditches, banks, and enclosures when viewed from above, particularly in the low-angle light of autumn or early morning. It was on photographs from that 1984 survey, catalogued as BGE 1/10,000, No. 0118, that the earthwork at Curraghturk was first identified as a potential site. It sits at the northern end of a conifer plantation, just south of a stream that marks the boundary between Curraghturk and the neighbouring townland of Spittle. By the time Digital Globe ortho-imagery was captured between 2011 and 2013, and again in subsequent Google Earth imagery, nothing remained visible at the surface. The site was compiled into the record by Martin Fitzpatrick and uploaded in October 2021.

For anyone curious enough to visit the general area, the townland of Curraghturk lies in County Limerick, and the approximate location near the plantation edge and townland boundary stream can be identified with the help of the aerial imagery referenced in the site record. There is, however, nothing to see in the conventional sense. The value here is less in what a visitor might observe and more in what the record itself represents: a trace of something, caught briefly in a photograph taken forty years ago during an industrial survey, that has since returned completely to the ground.
