This is a rath, the most common form of ringfort in Ireland, a type of enclosed farmstead built predominantly during the early medieval period, roughly between the fifth and twelfth centuries. What makes this particular example worth a closer look is the detail that survives in its structure, two concentric earthen banks separated by a V-shaped fosse, or ditch, with the inner bank measuring approximately 33 metres north to south and 32 metres east to west.

The inner bank still stands to around 0.8 metres in height and is best preserved along the arc running from north-northeast to south-southwest, where the inner face survives as a slight raised lip. The outer bank, also reaching roughly 0.8 metres, has been partially absorbed into the modern field fence system, a fate common to many such monuments where later farming generations found the earthworks convenient as ready-made boundaries. A narrow berm, a flat shelf of ground about 0.75 metres wide, runs along the inner face of the outer bank between northeast and northwest. There are two causeways, meaning deliberate gaps left in the banks to allow passage, one to the south-southwest forming the main entrance, wide enough at 3.6 metres through the inner bank and 4.2 metres through the outer, and a second, more modest break to the north-northeast. The two northern causeways are staggered rather than aligned, a detail that suggests considered design rather than simple convenience. The grass-covered interior slopes gently down towards the southwest, and the whole site remains under pasture.
