It exists, for most practical purposes, only from the air. The outline of the structure, a sub-oval shape measuring approximately 55 metres east-northeast to west-southwest and 38 metres north-northwest to south-southeast, betrays itself not through earthworks or stonework but through a thin band of dark green rushes that traces its perimeter across otherwise ordinary grazing ground, roughly 80 metres west of the Groody River. A cropmark of this kind forms when buried features, such as the filled-in ditches of an ancient enclosure, alter the moisture and nutrient content of the soil above them, causing vegetation to grow differently from its surroundings. Without that botanical clue, the site would be essentially invisible to anyone standing in the field.

The enclosure first came to official notice in 1986, when the Bruff aerial photographic survey captured it as a large suboval cropmark, recorded under the reference Bruff 275, AP 4/3712. That discovery placed it in a broader county-wide effort to document monuments that ground-level survey had missed entirely. The site was later confirmed through Ordnance Survey Ireland orthoimagery taken between 2005 and 2012, and again through Digital Globe aerial photography from 2011 to 2013, both of which showed the same distinctive rush-growth arc running from the east-northeast around the southern side to the west-southwest. The monument was compiled into the record by Alison McQueen and Vera Rahilly, with a formal upload date of 14 September 2020. Its age and original function remain unassigned in the available notes; the form is consistent with early medieval enclosures that once surrounded farmsteads or religious sites, but no excavation appears to have been carried out.

Access to this part of south County Limerick follows the low, quiet terrain of the Groody River valley, and the land around the site is working pasture. By 2018, Google Earth imagery showed that forestry planting had begun to the north and east of the monument, which may gradually change the character of the surrounding landscape and potentially affect how the cropmark reads from the air in future surveys. For anyone hoping to observe the feature on the ground, the dark rush growth is the only visible indicator, and it is most legible during drier months when the contrast between the rush-line and the surrounding grass is at its sharpest. The site carries no signage and no formal access, so the aerial images remain the most useful way to appreciate its shape and scale.
