A ringfort, or rath, was typically a circular enclosure bounded by one or more earthen banks and ditches, used as a defended farmstead by a family of some local standing. At this example in Dromin South, only portions of the outer ditch, called a fosse, survive: aerial photography shows it clearly defined from the south-southwest and from the west-northwest, but largely absent elsewhere, likely due to centuries of agricultural activity.

The monument appears on the 1897 edition of the Ordnance Survey Ireland twenty-five-inch map, where it is shown as a circular feature enclosed by a bank, the fosse already only partially present even then. Post-1700 field boundaries, visible on aerial photographs, have cut across the earthwork at the southeast and west, further disturbing its outline and making what survives all the more remarkable for still being legible. The site sits around eighty metres south of the townland boundary with Dromin North, and roughly three hundred and fifteen metres to the northeast lies Dromin church and its associated graveyard, a pairing of early ecclesiastical and secular monuments that is not unusual in the Irish landscape, where ringforts and early church sites frequently cluster within short distances of one another. A second possible ringfort lies just thirty metres to the northeast, raising the question of whether this was once a more densely occupied or socially significant patch of ground than its current pastoral quietness suggests.

The bank today is covered in scrub vegetation, which is itself a useful indicator when searching for the site from the ground; a thickened line of bushes and rough growth tracing a curve through an otherwise open field. A gap in the eastern side marks what appears to be the original entrance. Google Earth imagery from September 2019 shows the circular form clearly, and consulting that before a visit will give a useful sense of orientation. The site lies in private farmland, so access would require the landowner's permission.
