The church here has been recorded as a monument of interest, which in the Irish context can signal anything from an unusually early foundation to architectural features that set it apart from the run of nineteenth-century rural chapels built in the decades following Catholic Emancipation in 1829.

Beyond its classification, the specific history of this particular building remains difficult to reconstruct in detail at present. What can be said is that Garrynagry lies within a region where the Catholic Church re-established a visible physical presence only gradually after the Penal era, during which public worship was suppressed and churches were either repurposed or left to decay. The modest, functional chapels that followed emancipation were themselves sometimes replaced by more ambitious stone structures later in the nineteenth century, and it is into that broad pattern of rebuilding and consolidation that a church in this townland would most naturally fit.
