Beneath or around its foundations, a circular enclosure once occupied this ground, roughly thirty metres across, its southern edge already being clipped by a road when cartographers last recorded it in any detail. Today there is nothing to see. No earthwork, no ridge in the grass, no trace of the boundary that once defined this space.

The enclosure was marked on the third edition of the Ordnance Survey six-inch map, published in 1915, which means it was still a legible feature in the landscape at that point, however diminished. Circular enclosures of this kind are among the most common archaeological monument types in Ireland, typically interpreted as the remains of ringforts, the enclosed farmsteads of early medieval settlement between roughly the fifth and twelfth centuries. They survive in their thousands across the country, but an unknowable number have been lost to land clearance, road widening, and construction. At Kilcrin, the end came sometime in the early 1950s, when a bungalow was built on the site. Whatever the enclosure's original form, whether a raised earthen bank or a simple ditched boundary, nothing of it remained visible after that.
