It is the remnant of an ecclesiastical enclosure, the roughly oval boundary that once defined a sacred precinct, and it survives only partially, just enough to suggest what the full circuit would have looked like before later generations reshaped the ground around it.

The enclosure measures approximately 70 metres north to south and 50 metres east to west, and when the first detailed Ordnance Survey maps were made in 1838 it was recorded as circular, a common form for early Irish monastic or ecclesiastical sites where the boundary, known as a cashel or temenos depending on its material, enclosed a church, burial ground, and sometimes ancillary buildings. The southern arc of that boundary is still present as a bank roughly three metres wide and one and a half metres high, a modest but legible earthwork. The northern portion has been lost, removed at some point when the graveyard was extended and given its present rectangular form. The 19th-century church standing within the enclosure may itself overlie an earlier structure, though no physical evidence of that earlier building has survived above ground. Beyond the bank, nothing else remains to indicate how old the original foundation was or who established it.

What makes the site worth attention is precisely this layering of periods in a small space: an earthwork that predates the Ordnance Survey by an unknown span of centuries, a church that replaced something older, and a graveyard that has slowly consumed the very boundary meant to define it. The southern bank, modest as it is, holds the outline of a place that has been continuously adapted rather than simply abandoned.
