When the Ordnance Survey of Ireland produced its first detailed six-inch maps in 1840, this ringfort was not recorded at all, despite the surveyors being thorough enough to note a nearby pathway and the designed landscape south of Dromin Roman Catholic Chapel. It took until the 1897 twenty-five-inch edition for the monument to be formally acknowledged as an antiquity, suggesting it had either been obscured within a woodland plantation at the time of the earlier survey, or simply overlooked.

Ringforts, known in Irish as raths, are enclosed farmsteads typically built during the early medieval period, roughly between the fifth and twelfth centuries. They generally consist of a circular area surrounded by one or more earthen banks and ditches, and were used as protected homesteads for farming families. This example in Dromin South fits that familiar form. The 1897 map depicts a roughly circular enclosure with a diameter of approximately three chains and six metres, bounded by a bank on most sides, though the eastern section was already levelled by the edge of a woodland plantation by the time it was recorded. A second possible enclosure lies around forty-five metres to the west, suggesting this may have been part of a wider early medieval landscape. Satellite imagery from September 2019 shows the monument in reasonably good condition, with what appears to be an entrance on the southern side, and a later field wall cutting across the western portion and linking toward that neighbouring enclosure.

The site sits in pasture and is most clearly legible from aerial or satellite perspectives rather than from ground level, where the grass-covered field walls that now enclose it can make the original earthwork harder to read. Visitors approaching from the area south of Dromin Chapel, where the old pathway is still referenced on the historic maps, will find themselves near the townland boundary. The eastern bank is the most degraded section, worn down by the former plantation margin, so the clearest surviving elements are on the northern, southern, and western sides. Checking the OSi orthophotos or Google Earth imagery beforehand will help orientate a visit and allow the outline of the rath to be held in mind when walking the ground.
