Lime kilns were used to burn limestone down to quicklime, mainly for agricultural improvement of acidic soils, and finding one incorporated into the fabric of an earlier earthwork suggests the site had a working life long after its original occupants were gone.

The fort itself is a substantial example of the rath type, a class of enclosed farmstead that proliferated across Ireland during the early medieval period, roughly between the fifth and twelfth centuries. A rath typically consists of a circular area bounded by an earthen bank and an external fosse, or ditch, and this one is no exception. The enclosed area measures approximately 43.7 metres north to south and 45.9 metres east to west, ringed by an earthen bank rising to around 3.8 metres, with an outer fosse roughly 2.2 metres deep and a low secondary bank beyond that. A gap five metres wide breaks the inner bank on the eastern side, likely the original entrance. Inside, in the south-western quadrant, sits a circular hut site measuring roughly 7.1 metres by 12.6 metres, an oval footprint that would once have supported a domestic structure, probably a dwelling for the farming family who worked the land within and around the enclosure. Together, the dimensions and the double-bank arrangement suggest a reasonably well-defended homestead, though the lime kiln in the western bank points to later, more pragmatic reuse of the earthwork as convenient ready-made shelter or foundation material.
