What survives at Leamcon is modest: a circular earthwork about 36 metres in diameter, its defining bank now breached in numerous places and heavily overgrown with thistles. Yet even in this reduced state, a stretch of external stone-facing remains legible along the south-south-western to west-south-western arc of the circuit, suggesting the original construction was more substantial than the present condition implies.

Raths of this kind were the dominant settlement form in early medieval Ireland, typically enclosing a farmhouse, outbuildings, and perhaps a small garden plot, with the surrounding bank serving as a boundary marker and modest defensive barrier rather than serious fortification. The choice of a ridge, even a slight one, within low-lying marshy ground was deliberate; elevated positions offered drainage, visibility, and a degree of natural separation from the wetland around them. The stone-facing visible here hints at a builder with access to local material and reason to invest in a more durable structure, though without excavation it is difficult to say more about who occupied the site or when precisely it was in use.
