It measures roughly twenty metres east to west and ten metres north to south, barely enough of a rise to catch the eye unless you know what you are looking for. Yet the ground beneath it almost certainly holds the footprint of an early church, and the field around it may preserve the outline of the enclosure, typically a roughly circular or oval boundary, that early Irish ecclesiastical sites were so often defined by.

The site at Kilconnor appears in the Taxation of 1291, a papal survey of church properties across Ireland and England compiled under Pope Nicholas IV, which gives some sense of how established and recognised the place already was by the late thirteenth century. Writing in 1932, the scholar Power described it as a cillin or early church site, a term that in Irish usage can refer either to a small early medieval church or, in some contexts, to an unconsecrated burial ground used for unbaptised infants. Whether this site carried both meanings, or only the former, the notes do not say. What is clear is that the name Kilconnor, with its "kil" prefix derived from the Irish "cill" meaning church or cell, speaks to its ecclesiastical origins long before any written record does.
