A large oval earthwork, roughly 105 metres across its longest axis and 92 metres across its shorter one, sits in open grassland, its outline not obvious to anyone walking past but legible from above as a clear and deliberate shape pressed into the earth. It is the kind of site that reveals itself only through aerial or satellite imagery, invisible at eye level yet unmistakable once seen from altitude.

The enclosure was identified from Google Earth Pro satellite imagery captured in November 2005 by Jean-Charles Caillère. It appears to be defined by a scarp, meaning the boundary is formed not by a built-up bank but by a cut or drop in the ground surface, a subtler kind of earthwork that can erode into near-invisibility over centuries. A curving field boundary follows the outer edge of the enclosure along its south-southwestern to west-northwestern arc, suggesting that later agricultural divisions have partially absorbed or followed the older form. What makes the setting particularly interesting is the presence of a spring recorded on the first-edition six-inch Ordnance Survey map, positioned just outside the northeastern quadrant of the enclosure. On satellite imagery, a former stream bed is still traceable running from that spring toward the Dinin River, which lies roughly 125 metres to the southeast. The proximity of a water source to an enclosure of this size is a recurring pattern in early Irish settlement archaeology, where springs and streams often appear close to enclosed habitation or ceremonial sites, though whether this one served a domestic, agricultural, or ritual function remains an open question.
