The site, captured in aerial photograph GB 89.32, shows a circular enclosure marked by a wide fosse, or defensive ditch, with faint traces of a narrower outer fosse still visible from above. These cropmarks, which appear as variations in crop growth due to buried archaeological features beneath the soil, offer a tantalising glimpse into a landscape that has been thoroughly transformed by centuries of agricultural activity.

The circular earthwork is likely the remains of a levelled bawn, a fortified enclosure that would have once protected the nearby castle site (recorded as CW012-015). Bawns were a common feature of the Irish landscape during the plantation period, serving as defensive courtyards where livestock could be secured and local inhabitants could take refuge during raids. These structures typically consisted of high stone walls, sometimes with defensive towers at the corners, enclosing an area around a castle or fortified house.

While the physical structure has long since disappeared, likely dismantled for building materials or deliberately levelled for farming, the archaeological footprint remains etched into the landscape. The presence of both an inner and outer fosse suggests this was a substantial defensive work, designed to protect whatever stood at its centre. Today, only these subtle traces visible from the air hint at the strategic importance this site once held in the complex tapestry of Irish medieval and early modern history.
