On a gently eastward-facing slope at Monroe in County Tipperary, a circular enclosure once sat in rolling farmland, measuring roughly 26 metres across at its widest point. Today, nothing of it remains visible above the surface. The field boundaries that once framed the landscape have been cleared away, the ground given over to tillage, and whatever earthworks once defined the site have been reduced, by agriculture and quarrying, to near invisibility.

The enclosure is known primarily through the first edition Ordnance Survey six-inch map, produced in Ireland during the 1830s and 1840s, which recorded it as a circular feature. Circular enclosures of this kind are common across the Irish countryside and are typically understood as the remains of raths or ringforts, the enclosed farmsteads of early medieval Ireland, though some may be prehistoric in origin. By the time the later OS edition was produced, only a partial arc of bank was still marked, suggesting that the deterioration of the site was already well advanced. Quarrying nearby would have compounded the damage, eating into the surrounding ground and likely disturbing whatever subsurface archaeology remained.
