This enclosure, located in wet, poorly drained grassland in the townland of Cromwell, never made it onto the Ordnance Survey Ireland historic maps in any of their editions. It existed, in practical terms, as a shape in the earth that nobody had formally recorded until aerial observation changed the picture.

The site came to light during the Bruff aerial photographic survey of 1986, captured in an image catalogued as Bruff 118. From the air, the characteristic curving line of a ditch resolved into something recognisable: an enclosure, the kind of roughly circular or oval earthwork found across Ireland, often associated with early medieval settlement, though its date and function here remain unspecified in the record. Enclosures of this type are sometimes the eroded remnants of ringforts, the circular farmsteads that were once the dominant settlement form in early medieval Ireland, defined by an earthen bank and external ditch. Whether that applies here is unclear. What is clear is that the feature was invisible to cartographers working at ground level but legible from altitude. The curvilinear ditch has since been confirmed on Ordnance Survey orthophotos taken between 2005 and 2012, and on Google Earth imagery, lending consistency to the identification. Immediately to the south-west lies a second enclosure, recorded separately, and roughly 450 metres further south-west stands a ringfort annotated on older sources as Cromwell's Fort, a local name that likely reflects folklore rather than any documented Cromwellian military activity in the immediate area. The record was compiled by Martin Fitzpatrick and uploaded in April 2021.

Accessing the site requires some tolerance for soft ground. The poorly drained grassland that has helped preserve the ditch as a cropmark also means the area can be boggy underfoot, particularly in wetter months. The enclosure is not marked on standard walking maps, and without aerial or satellite imagery to hand it would be easy to walk across the area without recognising what lies beneath the surface. Consulting the relevant orthophotos beforehand, and cross-referencing the site's coordinates with the National Monuments Service records, gives the best orientation. The associated enclosure immediately to the south-west provides a useful secondary reference point when trying to locate the feature on the ground.
