The bank itself still stands nearly two metres high along its best-preserved stretch, running from the south-south-east around to the east, where its inner face has been reinforced with stone. This kind of enclosure, known in Irish archaeology as an early ecclesiastical enclosure, is essentially a boundary that once defined sacred or monastic ground, separating a community of religious life from the surrounding farmland. What makes Kilcolman quietly arresting is the way it has been absorbed into the working countryside: a farmyard now abuts the line of the enclosure to the east-south-east, and at that point the bank has been levelled away, the logic of the ancient boundary overwritten by the practical demands of agriculture.

The enclosure was identified as an early ecclesiastical site by Hurley in 1980, placing it within a category of monument that typically dates to the early medieval period in Ireland, roughly the sixth to twelfth centuries, when enclosed monastic and church settlements were a defining feature of the religious landscape. Within the south-east quadrant of the interior, there is the recorded site of Kilcolman church, now lost above ground but mapped as part of the same complex. The name Kilcolman itself, from the Irish "Cill Colmáin", suggests a foundation associated with Saint Colman, one of the most common dedications in Munster. Completing the picture of a place that accumulated sacred associations over time, a holy well lies just to the south-west, on the opposite side of the road from the enclosure. Holy wells in Ireland frequently predate Christianity or were absorbed into it early on, and their proximity to church enclosures is a recurring pattern across the country, suggesting layered use of the same ground across many centuries.

The enclosure sits in ordinary farmland and visitors approaching from the road would notice the bank most clearly along its north-east arc, where the stone-facing is visible. The holy well to the south-west, just across the road, offers a clear sense of how the two elements of the site relate to one another in the landscape, even now that the church itself has vanished.
