That anonymity is part of what makes the enclosure at Bohernagraga quietly arresting: it is the kind of site that exists in plain sight, visible for centuries to anyone walking the land, yet never formally acknowledged until relatively recently.

The enclosure was first identified during the Bruff aerial photographic survey in 1986, captured in survey image Bruff 1601 AP 4/3625 as a roughly circular earthwork measuring approximately 30 metres north to south and 33 metres east to west. Enclosures of this type, low circular banks or ditches usually forming a defined boundary around a central area, are a common feature of the Irish archaeological landscape, though their date and function vary considerably; some enclosed early medieval farmsteads, others served ritual or funerary purposes. The proximity of a ring-barrow, a burial mound encircled by a ditch, located about 60 metres to the north-east, suggests this part of Bohernagraga may have seen sustained use across a considerable span of time. The enclosure sits on poorly drained, reclaimed ground some 30 metres north-west of a small stream that feeds north-eastward into the Reask River, a setting that would have demanded management of water even in antiquity. Subsequent aerial photography, including OSi orthoimages from late 2005, Digital Globe images taken between 2011 and 2013, and a Google Earth capture from November 2018, has continued to reveal the earthwork with reasonable clarity from above.

Ground-level access to the site requires some care. The surrounding grassland is poorly drained, and conditions underfoot can be soft, particularly in wetter months. A modern drainage channel, visible in recent aerial photographs running outward from the centre of the monument toward the north-western stream, is a reminder that the land here has been actively managed and altered. Visitors approaching the site should be aware that the earthwork's outline is subtle at ground level, as is often the case with monuments of this kind, and that the surrounding landscape gives little indication of what lies within it until you are standing at its edge. The nearby ring-barrow, recorded separately in the Sites and Monuments Record, is worth locating during the same visit, as the two features together give a sense of how archaeologically layered this unremarkable-looking patch of south Limerick farmland actually is.
