The site is catalogued as a monument, meaning it has been formally recognised as a place of archaeological or historical significance, but the details that would tell us who built it, when it fell out of use, and what denomination or community it served remain, for now, out of easy reach.

The name Lugnakillew is itself suggestive. Place names in this part of Connacht frequently preserve older Irish forms, and the element "kill" or "cill" appears across Ireland in names associated with early ecclesiastical sites, derived from the Latin "cella", meaning a cell or small church. If the name follows that pattern, it may hint at a site with roots considerably older than the post-medieval period, though that remains speculation without firmer documentation. Curry parish sits in an area that saw significant population movement and land reorganisation across the seventeenth, eighteenth, and nineteenth centuries, and many small rural chapels in this region were built during the era of Catholic Emancipation or in the decades following, when congregations that had long worshipped in the open or in modest structures finally raised more permanent buildings. Whether this particular chapel fits that pattern is not currently clear from available sources.
