The only cartographic record of it comes from the 1910 edition of the Ordnance Survey six-inch map, where a curved arc, sweeping north to east to south, marks what was once a bank of roughly twenty metres. The name "Raheelin" is printed there in the gothic lettering that surveyors reserved for antiquities, a quiet signal that someone, at some point, considered this a place worth recording. A ringfort, in simple terms, is a circular or oval enclosure defined by an earthen bank and ditch, used in early medieval Ireland as a farmstead or place of habitation. This one, however, has left no trace that can be seen today.

By the time Michael J. Moore compiled the Archaeological Inventory of County Leitrim, published by the Stationery Office in Dublin in 2003, the site had already become a matter of inference rather than observation. It sits towards the bottom of an east-facing slope, within a coniferous plantation, and the ground yields nothing. The forest floor, likely reshaped by planting and the movement of heavy machinery over decades, has swallowed whatever earthworks once defined the enclosure. The 1910 map survives as the sole witness, its arc a faint geometric argument that something once stood here, organised and purposeful, in a landscape that has long since moved on.
