Known locally as ‘The Coreally’, possibly derived from the French ‘couralé’ meaning underground fortification, this rectangular enclosure once stood as a formidable defensive structure. First recorded on the 1839 Ordnance Survey map, the site measured approximately 55 metres north to south and 48 metres east to west, surrounded by an embankment that was, according to late 19th-century accounts, thickly covered with bushes and trees. Beyond this earthen rampart lay a water-filled fosse, or defensive ditch, stretching 10 to 12 yards wide, with the only entrance located on the south side.

Local tradition weaves tales of monks seeking refuge here from nearby Kilart nunnery and Kilberry church, whilst archaeological finds have included spearheads discovered in adjacent fields. Writing in the early 1900s, historian Darby noted the presence of what might have been a souterrain, or underground passage, within the interior; a cave that added to the site’s defensive capabilities and mysterious character. The monument’s physical presence was largely erased when, as Fitzgerald recorded, it was levelled years ago by a Scottish landowner named Maxwell, leaving behind only subtle traces in the landscape.

Today, the site reveals itself primarily through cropmarks visible in aerial photography, where differences in crop growth trace the lines of the ancient fosse and embankment. Photographs from the 1970s and a 1990 survey by Dr. Gillian Barrett clearly show the rectangular outline with its causewayed entrance midway along the southwest side. More recent Google Earth imagery from 2018 continues to capture these spectral impressions, along with a previously unrecorded enclosure about 600 metres to the north-northwest, suggesting this area held greater significance in medieval times than its current pastoral appearance might suggest.
