Overgrown and largely featureless to the casual eye, the enclosure is known locally for what it once held: the graves of unbaptised children. These sites, found across Ireland and often called cilliní, were the quiet, unofficial answer to a theological problem. Catholic doctrine long held that unbaptised infants could not be buried in consecrated ground, and so communities created their own marginal spaces, usually in old earthworks, ringforts, or on parish boundaries, where these children could be laid to rest. The grief was real; the ground, though unconsecrated, was not without care.

The enclosure at Laharan sits in gently west-sloping pasture and measures roughly 22 metres north to south and 25 metres east to west. Its outer bank of earth and gravel stands to about 0.9 metres at the northern arc, though dense vegetation makes even this much difficult to read from any distance. The interior offers little in the way of visible archaeology; the ground is stony and shows no obvious surface features. The site appears on both editions of the Ordnance Survey map as a circular enclosure, suggesting it was already a landscape fixture by the time systematic mapping began in the nineteenth century. Whether it originated as a prehistoric or early medieval earthwork that was later repurposed, as was common with cilliní, the notes do not say.
