The bank has largely vanished, a post-1700 field boundary cuts across its western side, and the rough pasture that surrounds it offers no obvious drama. Yet beneath that unremarkable surface lies evidence of layered occupation so precise that excavators could trace the outlines of rectangular houses as dark stains in the soil, and follow the silting of an underground passage through the quiet stratigraphy of centuries. This is the kind of place that rewards attention paid to what is no longer visible.

The ringfort sits within a much larger archaeological complex on what antiquarian Thomas Johnson Westropp identified, writing between 1917 and 1919, as the supposed site of Temaír Erann, the ancient cemetery of the Ernai tribe on Slievereagh. The surrounding landscape is dense with related monuments: an earthwork lies immediately to the south-east, and a second ringfort, designated a National Monument, stands roughly twenty metres to the east. This particular fort, recorded as Ringfort No. 10 in the Northern Group, was excavated by Seán P. Ó Ríordáin in 1934 and 1935. A ringfort, sometimes called a rath, is a circular enclosure defined by earthen banks and ditches, widely used as a farmstead during the early medieval period in Ireland. Ó Ríordáin found that the inner bank had disappeared entirely, though excavation located the inner fosse, a defensive ditch, and even a remnant of stone facing on its inner edge. A souterrain, an underground stone-lined passage typically used for storage or refuge, was uncovered, along with wall-grooves just twenty centimetres below the surface that outlined rectangular houses. One of those houses, the excavation evidence suggested, had still been in use after the souterrain had already silted up and been abandoned.

The site sits in the northern corner of a field in rough pasture, and its outline, approximately twenty-seven metres in diameter, can be picked out on aerial imagery even where it eludes the eye on the ground. The western arc is interrupted by field boundaries that post-date 1700, so the full circuit is only legible from above. Visitors should look for the companion monuments nearby, particularly National Monument No. 663 to the east, which gives a clearer sense of the scale and density of this complex. Low winter light, when shadows throw shallow earthworks into relief, is the most useful condition for reading what survives.
