That much is recorded. Beyond the bare designation of its site, however, the details are sparse, and the place occupies that particular category of Irish ecclesiastical history where the physical evidence has receded and the documentary record has yet to catch up.

Catholic church sites of this kind often belong to the penal or post-penal period in Irish history, roughly the late seventeenth through the nineteenth centuries, when Catholic worship moved from improvised outdoor mass rocks and borrowed land into purpose-built, if modest, structures as legal restrictions on Catholic practice were gradually lifted. Many such churches were later superseded by larger Victorian-era buildings and simply abandoned, leaving a field, a fragment of wall, or a slightly uneven patch of ground as the only indication that a congregation once gathered there. Without further documentation it is not possible to say when the Barleyfield church was built, by whom it was served, or why it fell out of use, but its classification as a recorded monument suggests it retains some archaeological or historical significance in the landscape.

The site is noted but not yet fully documented in publicly available form, which means visitors and researchers will find little by way of interpretive material on the ground or online. What remains at the location itself is similarly unconfirmed from available sources.
