What makes it slightly unusual among Kerry's many raths is its bivallate construction, meaning it was originally defended by two concentric banks rather than the single bank more commonly encountered. That doubled effort suggests the enclosure and whatever domestic or agricultural activity it sheltered mattered enough to warrant the additional labour.

The structure follows the standard rath form, a circular raised platform enclosed by a fosse, which is simply a broad defensive ditch, but here the numbers tell a particular story. The inner area measures roughly 21 metres north to south and 22 metres east to west, sitting about a metre above the surrounding boggy ground. Around that platform runs a fosse between 7 and 11 metres wide, and beyond it an outer bank some 7 metres across, rising between 0.6 and 1 metre above the fosse and nearly 1.8 metres above the general ground level. That outer bank survives clearly on the western, northern, and eastern sides, though it has been lost or eroded elsewhere. The measurements were recorded by C. Toal as part of the North Kerry Archaeological Survey, published in 1995, which catalogued this site as entry number 362.
