There is nothing to see of it now. No earthwork, no ditch, no upstanding bank; just lawn or flower beds or whatever a suburban garden might hold. The only evidence that anything ever existed here is cartographic, and even that record charts a disappearance rather than a presence.

The 1837 Ordnance Survey six-inch map shows the enclosure clearly, drawn as a complete circle roughly twenty-five metres in diameter. By the 1913 edition, only a hachured arc marking the western half remained, the rest presumably levelled or obscured by that point. Circular enclosures of this kind are among the most common monument types in the Irish landscape; they typically functioned as enclosed farmsteads or ringforts, the everyday settlements of early medieval rural life, defined by an earthen bank and outer ditch. Most were built and occupied between roughly the fifth and twelfth centuries, though many remained in use or were modified long after. What purpose the Knockaculleen example served, who built it, and when it was lost are questions the surviving record cannot answer. What it can offer is one quietly telling detail: a property boundary in the area appears to follow the original north-west to west curve of the enclosure, as though the land division that replaced the monument retained some memory of the shape it erased.
