Three successive Ordnance Survey editions, from 1842 through to 1938, show the same hachured circle, the conventional symbol used to indicate a raised earthen enclosure. By the early 1980s, according to local memory, the rath had been levelled, most likely as part of agricultural improvement work.

A rath, or ringfort, is an enclosed farmstead of the early medieval period, typically defined by one or more earthen banks and ditches thrown up around a central living area. Thousands survive across Ireland in varying states of preservation, but a considerable number have been lost to exactly this kind of clearance, particularly during the decades of intensive land improvement that followed government incentives to bring marginal ground into production. The Kilcolman example was a modest one, measuring roughly 29 metres east to west and 27.5 metres north to south, placing it within the typical size range for a single-family agricultural enclosure of its type.

What remains today is subtle. The ground still holds a faint circular rise, just enough to trace the outline of where the bank once stood. Scattered across this area is a notably greater concentration of stones than appears in the surrounding field, the kind of detail that passes unnoticed unless you are looking for it. The site sits in tillage, so access is not straightforward, but the hilltop position means the enclosure would once have been a prominent local landmark, visible at a distance in the way that many ringforts deliberately were. The maps record what was there; the stony soil remembers it in its own way.
