No road sign points to it, no heritage plaque marks it, and the townland boundary between Doonvullen Lower and Doonvullen Upper has quietly absorbed part of its southern edge, running along it as though the enclosure were simply a convenient line in the ground rather than a feature that predates the administrative geography laid over it.

The enclosure, an enclosed area defined by an earthen bank or similar boundary, typically associated with early medieval settlement or agricultural use in the Irish landscape, measures approximately 77 metres north to south and 74 metres east to west. It went unrecorded on historic Ordnance Survey Ireland mapping and only came to formal attention through aerial observation. The Bruff aerial photographic survey identified it in 1986, captured on photograph AP 4/3689. A decade later, the Discovery Programme, a state-funded archaeological research body established to investigate Irish prehistory and early history, recorded it again through the McCloud photographic survey of 1996. The site sits alongside two neighbouring enclosures: one lies roughly 20 metres to the south-west, and another abuts its southern margin directly, suggesting this corner of Limerick may once have supported a cluster of associated activity rather than a single isolated feature. The record was compiled by Edmond O'Donovan and uploaded in September 2020.

The site is not accessible in any formal sense, and the waterlogged character of the pasture means the ground underfoot can be difficult depending on the season, with wetter months likely making approach more problematic. It is overlooked to the east by a hill, which means the enclosure itself would have had open sightlines in most directions, a quality sometimes associated with deliberate placement in the Irish archaeological record. The clearest view of the enclosure's form remains an aerial one; it is visible on Google Earth imagery from June 2018, which offers the most practical way to appreciate its scale and relationship to the neighbouring enclosures before, or instead of, any visit on foot.
