The 1837 OS Fair Plan recorded it as a circular enclosure annotated simply as "Track of fort", and the six-inch map of the same year confirmed that outline. Today the fort has been levelled entirely, and what remains is only a cropmark: an oval patch of greener grass, roughly 20.5 metres north to south and 16.4 metres east to west, with faint humps and hollows in the interior and vague traces of old cultivation ridges running northeast to southwest.

Ringforts are enclosed farmsteads of early medieval Ireland, typically defined by an earthen bank and ditch, and this one carried an additional curiosity beneath its surface. Local knowledge, recorded in 1972, described a stone covering a cavity in the northern quadrant of the enclosure. That cavity is thought to indicate a souterrain, an underground passage or chamber often built within ringforts for storage or concealment. The same local tradition held that the land had once been owned by monks, though no documentary evidence is cited to confirm this. The name Shankill, which appears on the 1837 map as the field name, derives from the Irish "Seanchill", meaning old church, a name that recurs across Ireland and frequently points to early ecclesiastical activity in the area. Whether the monastic association is genuine memory or later interpretation is impossible to say now. Modern farm buildings have since been constructed on the north-northeast quadrant of the levelled fort, further obscuring whatever might remain underground.
