The enclosure is oval in plan, roughly 120 metres along its north-east to south-west axis and around 60 metres across, and that shape alone carries meaning. Ecclesiastical enclosures of this kind, typically a boundary bank or wall demarcating sacred ground from the world beyond it, are one of the most recognisable features of early Christian monasticism in Ireland. Most have been reduced, over centuries of farming, to exactly this: a faint arc here, a grassed-over bank there.

What makes Lecarrow more than just an eroded earthwork is the cluster of associated features that survive nearby. A church, a children's burial ground, and two holy trees or wells have all been recorded in the immediate area. Children's burial grounds, sometimes called cillíní, were used for infants who died unbaptised and could not, under older Church practice, be interred in consecrated ground; their presence close to an enclosure often points to a site with deep, layered use over many centuries. The holy trees and wells suggest a continuity of veneration that may predate Christianity itself, absorbed rather than erased by the new faith. And then there is the name of the townland immediately to the east: Kilmurry, from the Irish Cill Mhuire, meaning the church of Mary. Place-names of this type are frequently the most durable evidence of early ecclesiastical activity, outlasting the physical structures by a millennium or more. Together, these details point towards a possible early Christian monastic settlement, though the archaeological record as it stands cannot confirm this with certainty.
