Yet the geometry tells a different story. The enclosure measures roughly 21 metres north to south and just over 17 metres east to west, with a broad encircling bank and a shallow flat-bottomed fosse, the term for a ditch that typically accompanies such earthen boundaries, running around its outer edge. Neither the bank nor the fosse is dramatic by any measure; the bank stands only about half a metre above the fosse at its highest, and in places it has been reduced to little more than a scarp, a sloped edge where the original upcast material has settled and eroded over time.

Enclosures of this kind are found throughout Ireland, and while their precise function varies, many are thought to be early medieval in origin, serving as ringforts or livestock enclosures, or in some cases marking a more ceremonial or domestic space. This particular example retains traces of an entrance roughly four metres wide in its southern quadrant, along with what may have been a causeway crossing the fosse to allow access. Some disturbance in that area has blurred the picture, with bank material apparently having slipped into the ditch. A secondary raised area within the western interior, measuring about eight by six metres, hints at some internal organisation, though its purpose is not clear. To its north, a cluster of flag irises has taken hold, their presence a reliable signal that water sits close to the surface. A field drain running northward from the fosse suggests that someone, at some point, made a practical attempt to manage the waterlogged ground around it.
