In the low-lying pastureland of Killure Beg, County Galway, a roughly subcircular enclosure stretches approximately 99 metres north to south and 92 metres east to west, its outline traced cleanly on aerial photographs. Walk the same ground, though, and almost nothing announces itself. The earthwork that once defined this space has been so thoroughly reduced by time, farming, and the slow settling of the soil that what remains is barely a whisper in the landscape.

When investigators visited the site in March 1985, they found only tentative traces of what was once an ecclesiastical enclosure, the kind of roughly circular or oval boundary, typically an earthen bank or fosse, that early medieval Irish churches and monasteries often used to define sacred space and mark a boundary between the secular world and the precinct within. The best they could identify on the ground was a degraded earthen bank located about 46 metres to the north of an associated church, and even that reached a maximum height of just 0.2 metres, barely ankle height, its edges too indistinct to measure with any confidence. A modern field boundary running north to south cuts through the eastern side of the enclosure, further complicating any reading of the original form. Inside what would have been the enclosed area, the remains of the church itself survive alongside a children's burial ground. Such burial grounds, known in Irish as cilliní, were used in post-medieval centuries for infants who died before baptism, and their presence here alongside an earlier ecclesiastical structure points to a long, layered history of this place as a site of religious significance.

The aerial photograph remains the most legible way to appreciate the full extent of the enclosure, since the complete outline, invisible underfoot, resolves clearly when seen from above. Visitors to the general area should expect to find very little on the surface beyond the church remains and the burial ground; the enclosure itself survives more as a cropmark or soil anomaly than as any upstanding feature.
