What gives it away is the fosse, a term for a defensive or boundary ditch, which traces a rough circle approximately 34 metres in diameter. The outline is subtle enough that it was only formally recorded from an aerial photograph, specifically an Ordnance Survey Ireland orthophoto taken in December 2005, when the angles of winter light and soil moisture brought the cropmark or ground depression into relief.

The enclosure sits on reclaimed grassland, meaning the land has at some point been drained, cleared, and turned over to agricultural use, a process that tends to flatten and obscure earthworks over time. Just to the north-northeast lies an unclassified barrow, the term for a burial mound or funerary earthwork, catalogued in the Sites and Monuments Record as LI023-100. The two features sit close enough together to suggest this corner of Cloghaviller was a place of some significance in the past, though without excavation it is impossible to say how the enclosure and the barrow relate to one another, or indeed what period either belongs to. The site was compiled by Alison McQueen and Vera Rahilly, with the record uploaded in August 2020.

Because the enclosure is visible primarily from the air rather than the ground, a visitor should not expect a dramatic earthwork. The fosse has been reduced by centuries of agriculture, and what remains is a gentle depression rather than a bold earthen ring. The surrounding area is working farmland, so access would require local permission. Those with an interest in landscape archaeology would do well to look at the OSi aerial layer before visiting, since understanding what you are looking for makes all the difference when the feature itself is this understated. The nearby barrow is equally low-key, and the two together offer a quiet example of how much of Ireland's early landscape survives not as visible monument but as faint impression, recoverable only when the conditions happen to be right.
