What survives of this enclosure in Dromin South is roughly semi-circular in shape, a bank running from the south-west around to the north-west before petering out, the rest of the outline long since levelled by agriculture or time. It measures approximately 37 metres north to south and 45 metres east to west, and its identity remains genuinely unresolved. It may be an early medieval ringfort, the kind of circular earthwork, typically defined by one or more banks and ditches, that once served as a farmstead enclosure across Ireland. Or it may be something else entirely, a deliberate landscape feature installed by whoever was shaping the grounds of a nearby estate some time after 1700.

The historical maps are where this ambiguity becomes interesting. The first edition Ordnance Survey six-inch map of 1840 does not show the enclosure at all, which is notable given that the same map records a pathway connecting the area to a designed landscape situated just south of Dromin Roman Catholic Chapel. By the time the 25-inch map was published in 1897, the feature appears as an irregular-shaped woodland area enclosed by field walls, sitting within a plantation. A later Cassini edition of the six-inch map adds partial hachuring, the cartographic shorthand for a slope or earthwork, but only on the western arc. Forty-five metres to the east lies a separate, possible ringfort recorded in the Sites and Monuments Record. A field bank running east to west intersects the enclosure on that side, connecting the two features. Whether the enclosure was originally an early ringfort later pressed into service as a tree-ring or ornamental planting circle, or whether it was constructed as a landscape feature from the outset to complement the plantation, the maps alone cannot settle the question.

The enclosure sits in pasture just south of the boundary between Dromin South and Dromin North. Its outline, no longer visible from ground level in any complete way, can be picked out on aerial orthophotos from the 2005 to 2012 period as well as on a Google Earth image from September 2019, which gives some sense of how to orient yourself before visiting. Access is across farmland, so landowner permission would be the necessary first step. Those with an eye for subtle earthworks may be able to trace the surviving bank on the western side; the eastern portion has been largely absorbed into the surrounding field system. The nearby ringfort to the east, though also poorly preserved, is worth noting as a separate feature rather than assuming the two form a single monument.
