These enclosures, built mainly between the early medieval period and around the twelfth century, served as farmsteads for individual families, their raised banks and ditches defining a domestic and agricultural space rather than a purely military one. What makes this particular example quietly absorbing is the way it has been half-absorbed into the working landscape around it, its defining earthworks folded into a field boundary and worn down to the point where the original entrance has become impossible to identify.

The enclosure measures around 36.2 metres in diameter. On its north-east to south-facing arc, a bank of earth and stone survives to a reasonable height of 1.3 metres, with a width of nearly 5.8 metres. Beyond it lies an external fosse, the shallow ditch that would originally have complemented the bank as a combined barrier, though here it is wide and gentle, measuring about 5.5 metres across and only 0.3 metres deep. On the remaining sides, the boundary reduces to a scarp, a low natural or constructed slope, ranging from barely perceptible at 0.1 metres to around 0.55 metres in places. The interior itself is not flat; it tilts noticeably from south-east down to north-west, following the natural gradient of the hillside on which it sits. That slope, looking out over the lough below, would have made this a reasonably commanding position for whoever once farmed and lived within it.
