This circular enclosure in Grange Upper, County Limerick, received no such treatment. Instead, surveyors rendered it with a plain solid line, identical to the hedgerows and ditches around it, effectively classifying it as a non-antiquity. That early dismissal has shaped the monument's fate ever since.

The reason for the surveyors' scepticism is plausible enough. The 1838 map shows the interior of the roughly circular earthwork planted with trees, which points toward a post-1700 tree-ring, a deliberate planting arrangement common on improving estates of the eighteenth and early nineteenth centuries, rather than anything older. Ringforts, the circular enclosed farmsteads that pepper the Irish countryside and date broadly from the early medieval period, were well known to OS mapmakers, and this feature apparently did not read like one to them. By the time the later 25-inch OS map was produced in 1897, the enclosure was recorded more carefully, described as a circular-shaped area of approximately 50 metres internal diameter, defined by a scarp, essentially a low earthen slope marking its edge. Whether the planting had by then been cleared, or whether the later surveyors simply looked harder, is not recorded. What is certain is that a ringfort does exist nearby, some 157 metres to the east, suggesting the landscape here has layers of use across very different periods.

Today the monument sits immediately north of a working farmyard, and the southern half of the enclosure has been further obscured by modern farm buildings and a silage pit. The remainder is heavily overgrown with scrub. Aerial imagery from 2011 to 2013, and again from late 2019, shows the outline still faintly legible from above, though on the ground it requires some patience to read. This is not a site with interpretive panels or a car park; it is the kind of place that rewards those comfortable with peering through brambles and cross-referencing old maps, the faint arc of a scarp line doing quiet work against the noise of a functioning farm.
