It is not a rath or a ringfort in the conventional sense, but something larger and more geometrically deliberate, a trapezium-shaped enclosure of considerable scale that has largely escaped wider attention.

The most detailed description of the site comes from O'Kelly, writing in 1942 to 1943, who recorded its layout with some precision. The enclosure measures roughly 128 metres north to south and 91 metres east to west, making it substantially larger than the typical early medieval farmstead enclosure. It consists of an outer bank with a fosse on its inner side, a fosse being a ditch of the kind commonly used in defensive or boundary earthworks, with a raised open space inside that, edged by a second bank. The interior is further divided into three distinct areas, two smaller and one large, by internal banks that had already become barely perceptible by the time O'Kelly examined them. The entrance sits at the middle of the west side, formed by a 4.5-metre gap in both the inner and outer banks, with a sloping causeway leading across the fosse. The main construction is earth and gravel, though stone appears to have been incorporated into the internal dividing walls. Aerial photographs held by the Archaeological Survey of Ireland, taken in September and October 2002 and again in March 2006, give a clearer sense of the overall form from above, where cropmarks and slight earthwork shadows can reveal what ground-level inspection alone might miss.

The site lies within the Smallcounty barony of County Limerick. Because the internal banks are now only faintly visible, a visitor arriving without prior knowledge of the plan might struggle to read the full complexity of the interior. The outer banks and entrance gap are the most legible features on the ground. Aerial photographs, accessible through the Archaeological Survey of Ireland's online records, are worth consulting before a visit, as they provide useful orientation for what to look out for once you are standing inside.
