It measures approximately 31 metres north-west to south-east and 35 metres north-east to south-west, and its outline, most legible from the air, traces a penannular shape, that is, a near-complete ring with a gap, rather than a fully closed circle. What makes it curious is not dramatic topography or obvious antiquity, but the gap between what the land shows and what the maps record: the enclosure does not appear on any edition of the Ordnance Survey historic mapping, even though buildings are consistently shown within the same area across all map editions.

The earthwork was first formally identified during the Bruff aerial photographic survey of 1986, recorded as image AP 4/3676 in the Bruff 115 series. That survey flagged it as a penannular-shaped earthwork, a form more commonly associated with early medieval ringforts, though the evidence here points in a different direction. The working interpretation, compiled by Alison McQueen and Vera Rahilly and uploaded to the record in July 2020, is that this could be the remains of a post-1700 tree-planted enclosure, the kind of ornamental or functional boundary planting that sometimes accompanied farmsteads of the eighteenth or nineteenth century. If that reading is correct, it would make this a relatively recent landscape feature in archaeological terms, one that simply was not captured in the cartographic record despite the farmstead itself being mapped. A second possible enclosure sits roughly 110 metres to the north-west, which adds a degree of complexity to the picture without yet resolving it.

The site sits in ground that is described as wet and partially reclaimed, which is worth bearing in mind for anyone who tries to approach it on foot. The tree-lined oval is visible on Digital Globe orthophotos from 2011 to 2013 and partially legible on Google Earth imagery from June 2018, so satellite views remain the most reliable way to get a sense of its shape and scale before visiting. On the ground, the enclosure is likely to read as little more than a ring of mature trees in a damp field, the earthwork itself subtle beneath the vegetation. The townland boundary with Brackyle runs close by, and that edge between named places is itself a useful navigational marker in otherwise featureless pasture.
