The Ordnance Survey Fair Plan labels the site 'Meelisheen', while the Ordnance Survey Name Books record it as 'Flat Fort', a loose translation of Maol Lios, or Lisín, meaning a low or levelled enclosure. The name itself carries a quiet irony: the fort's modest profile had already, it seems, shaped how people understood it long before modern earthmoving finished the job.

What made the site archaeologically interesting was not only the ringfort itself but a curved field boundary running along the southern side of a nearby house. Noted by Ó Cíobháin in 1978, the boundary followed a semicircular outline suggestive of an earlier circular enclosure, possibly a remnant of the original rath preserved incidentally within a later agricultural landscape. That boundary has since been levelled, erasing whatever structural evidence remained. Ringforts, which were typically enclosed farmsteads of the early medieval period, often survive only as crop marks or field anomalies once the earthworks themselves are gone, so the loss of that curving boundary represents a small but real reduction in the readable archaeology of the area. On the eastern side of the main site, however, something more substantial persists: a stone-built souterrain, an underground passage or chamber used in early medieval Ireland for storage or refuge, consisting here of three separate chambers. The second edition of the Ordnance Survey map marked this feature simply as 'Cave', which hints at how long it has been known locally without being fully understood for what it is.
