No local tradition marks it, no earthwork breaks the surface, and only a nineteenth-century map betrays its existence. The 1839 edition of the Ordnance Survey six-inch map shows a small rectangular form, roughly thirty metres along its longer axis and twenty metres across, hemmed in on three sides by straight field banks at the south-west, north-west, and north-east. The ground today gives nothing away.

The site is classified as a moated site, a category that refers to a rectangular enclosure, typically medieval in date, surrounded by a water-filled or dry ditch and an accompanying bank. In Ireland, moated sites are generally associated with Anglo-Norman settlement from the thirteenth and fourteenth centuries, often marking the farmsteads or small manorial centres of settler families rather than major fortifications. The Curraghduff example was identified as such by T. B. Barry in 1977, and its dimensions, modest even by the standards of the type, suggest a minor agricultural or domestic enclosure rather than anything grander. That it was already constrained by field banks when the Ordnance Survey recorded it in 1839 implies the surrounding landscape had long since been reorganised around it, gradually absorbing and obscuring whatever earthworks once defined it.

What makes the site quietly unsettling is the completeness of its disappearance. There is no local knowledge of an antiquity here, which means that whatever function this enclosure once served, whatever household or small estate it once contained, has been entirely forgotten at the local level. The map is the memory now.
