It has no marker, no signage, and no official record in the conventional cartographic sense. It exists, instead, as a partial cropmark, the kind of thing that only becomes legible when you are high above it and the soil beneath is dry enough to betray what lies underneath.

The site came to light not through excavation or archival research, but through aerial photography commissioned during the routing of the Bórd Gáis Éireann Curraleigh West-to-Limerick gas pipeline. Photographs taken on 3 November 1984, catalogued under Strip Map 4, Site 4/16, revealed a rectangular enclosure with a circular-shaped internal feature, sitting within what appears to be a possible field system. The enclosure measures approximately 31 metres north to south and 29 metres east to west, making it a modest but reasonably substantial structure. Cropmarks, for readers unfamiliar with the term, appear when buried features such as ditches or walls affect how plants grow above them, with differences in soil moisture and depth producing subtle variations in vegetation colour or height that are invisible at ground level but legible from the air. Subsequent orthophotographs taken by Ordnance Survey Ireland between 2005 and 2012, and a Google Earth image dated 28 June 2018, have confirmed the partial outline is still detectable. The site sits around 60 metres south of a watercourse that forms the townland boundary with Knocklong East, and was compiled in the archaeological record by Fiona Rooney, uploaded in July 2021.

There is nothing to see here in the conventional sense. The earthwork lies in ordinary-looking farmland and offers no visible structure above ground. Its interest is almost entirely aerial and archival. For those curious enough to consult the Ordnance Survey Ireland orthophotographs or pull up the relevant Google Earth coordinates, the faint rectangular shadow of the enclosure can be made out in the right conditions. The surrounding landscape, flat and damp, is the kind of ground that tends to preserve buried archaeology well precisely because it has been so thoroughly transformed by drainage and agricultural improvement.
