The cluster of houses gathered around the local church is ringed by a circular field system, and when you trace that system on a map, the outline that emerges is not a random arrangement of land divisions but the ghost of an early ecclesiastical enclosure, roughly oval in shape and measuring approximately 200 metres east to west and 160 metres north to south. The enclosure is the kind of feature that tends to go unnoticed precisely because it has been absorbed into the ordinary fabric of the countryside.

Ecclesiastical enclosures of this type are a characteristic feature of early medieval Irish Christianity, marking the boundary of a monastic or church settlement that would have contained not just a place of worship but a working community. The boundary at Cloonown survives in partial form as stone walls and hedgerows along its south-eastern to south-western arc, and its shape was visible on both the 1837 and 1915 editions of the Ordnance Survey six-inch map, suggesting the pattern has persisted across the landscape for a very long time. Perhaps the most telling detail is what lies just outside it. Around 50 metres beyond the enclosure's north-western line, evidence of metal-working has been identified. It was common practice in early Irish ecclesiastical settlements for craft activity, including smithing and metalwork, to be conducted in a zone immediately outside the main boundary, close enough to serve the community but kept at a deliberate distance from the sacred interior. That spatial logic, preserved here in soil and field boundary alike, quietly maps out a settlement pattern that has otherwise long since vanished.
