The fosse, a defensive or boundary ditch, measures some 3.5 metres wide and encloses a roughly circular area nearly 100 metres across. That near-perfect circularity is itself a quiet signal: early Irish monastic foundations were frequently laid out in circular or oval enclosures, a pattern that distinguishes them from the rectilinear logic of later medieval and post-medieval settlements.

Within the enclosure there survives both an ecclesiastical building and a cillin, or children's burial ground, the latter a feature found across Ireland at sites where unbaptised infants and others excluded from consecrated ground were interred, often over long stretches of time. The enclosure sits on a slight rise overlooking bogland to the west, a modest but deliberate elevation that would have given early inhabitants both drainage and a degree of visibility across the surrounding landscape. References from O'Flanagan in 1927 and from Gwynn and Hadcock's survey of medieval religious houses in 1970 confirm the site's recognised status in the scholarly record. The fosse is not entirely intact: a modern field boundary has obliterated it between the south-south-east and south-south-west, and another section to the north-west appears to have had its course straightened at some later point, evidence of the quiet, incremental ways in which agricultural use reshapes ancient boundaries over generations.

Two holy wells lie along the approach roads to the site, one roughly 490 metres to the south-south-east and another about 750 metres to the north-north-east. Holy wells in Ireland were often associated with patron saints and with patterns, the local devotional gatherings held on a saint's feast day, and their clustering around an ecclesiastical enclosure like this one suggests that the religious landscape here once extended well beyond the ditch itself, threading outward along the roads and across the bogland in ways that no longer read clearly on the surface.
