At Dromin in County Limerick, a large circular enclosure once marked the landscape clearly enough to be recorded on the Ordnance Survey's six-inch map of 1841, yet today the structure itself has been almost entirely erased. What remains is a short arc of fosse, the ditch that once ran around the enclosure's perimeter, now no more than 0.45 metres deep and 1.25 metres wide, curving for roughly 46 metres through pasture on a gently north-west-facing slope before being cut off at both ends by a north-south field boundary.

The 1841 OS mapping shows the original monument as an embanked circular enclosure approximately 110 metres in diameter, which would have made it a substantial feature. Enclosures of this type are common across Ireland and typically date from the early medieval period, though some have prehistoric origins. They are often referred to as ringforts, the bank and fosse serving to define a farmstead or settlement and perhaps to keep livestock in and predators out. At 110 metres across, this example would have been on the larger end of the scale, suggesting it may have been a site of some local significance. The record was compiled by Denis Power and uploaded in August 2011, drawing on both the historic cartographic evidence and a ground survey that confirmed how little now survives above the surface.

The site lies in pasture, so access will depend on the landowner's permission, and there is nothing to indicate its presence from a road or public path. Visitors who do make their way to the field should not expect an obvious earthwork. The fosse arc runs roughly south to south-west and is best read as a slight depression in the grass rather than anything more dramatic. The truncating field boundary is the most useful landmark, as the ditch simply stops where the boundary crosses it. The value of the site lies less in what can be seen and more in what the cartographic record preserves: the outline of something large and deliberate that the landscape has since quietly absorbed.
