At Laghcloon, a low subcircular platform, measuring roughly 17 metres north to south and 14 metres east to west, and standing no more than a quarter of a metre above the surrounding ground, is all that remains visible of a rath, the Irish term for a ringfort. These were typically the enclosed farmsteads of early medieval landowners, defined by one or more earthen banks and ditches that marked out a domestic and agricultural territory. Here, the earthworks have been reduced to three short stretches of bank along the platform's perimeter, each barely a metre wide and fifteen centimetres high. What was once a boundary enclosure has become almost indistinguishable from the undulations of ordinary farmland.

The site sits near the bottom of a south-facing slope, roughly 45 metres east of a stream. The wet ground around the platform is thought to indicate the former presence of a fosse, the encircling ditch that would originally have complemented the earthen bank and given the rath its defensive or demarcating character. The interior of the platform is level, with no visible trace of the structures that once stood within it. Despite this near-invisibility on the ground, the rath was recorded on the Ordnance Survey's six-inch map of 1840, where it appears marked with hachures, the short lines surveyors used to indicate raised earthworks, suggesting it was more legible in the landscape at that time than it is today.
