It does not appear on Ordnance Survey Ireland's historic maps at all, which is part of what makes it quietly puzzling. The enclosure only came to wider attention through aerial photography, and it has been quietly accumulating documentation ever since, largely invisible at ground level to anyone who did not already know to look.

The site was first formally identified during the Bruff aerial photographic survey of 1986, recorded under the reference Bruff 21 AP 4/3621. From the air it presents as a sub-rectangular earthwork, meaning it is broadly rectangular but with enough irregularity to suggest organic origins rather than precise planning, measuring approximately 32 metres north to south and 29 metres east to west. An enclosure of this kind, a defined area bounded by a raised earthen bank or ditch, was a common feature of early Irish settlement and farming life, used variously for habitation, livestock management, or ritual purposes. What makes this one especially layered is that a later relic field boundary cuts directly through it on a northwest to southeast axis, indicating that at some point the enclosure fell out of use and the land was reorganised around and across it. The site sits within a broader field system and lies roughly 100 metres southeast of a separate recorded enclosure, suggesting the landscape here was once considerably more structured than its present appearance implies. Edmond O'Donovan compiled the formal record, uploaded in September 2020, drawing on imagery from OSi orthoimages taken between 2005 and 2012, Digital Globe imagery from 2011 to 2013, and a Google Earth image dated November 2018.

The enclosure lies approximately 18 metres north of the townland boundary with Castlelloyd, on flat pasture in the barony of Coonagh. Because it is not marked on historic maps and survives only as a subtle earthwork, it is not the kind of place that resolves itself into anything obvious on the ground. The bisecting field boundary further complicates the outline. Aerial or satellite imagery remains the most reliable way to read the shape clearly, and Google Earth's historical imagery layer allows you to see the site as it appeared in 2018. For those visiting the broader area around Bruff, the enclosure is a reminder that the fields here carry a great deal of archaeology that simply has not yet surfaced into the public record.
