It is the kind of structure that survives not through fame or restoration but simply by remaining, its form intact enough to read, its function long gone.

Constructed in 1812, the building follows a layout common to Church of Ireland parish churches of the period: a rectangular body with a tower at the western end, a chancel projecting to the east, and a vestry tucked against the northern side of the chancel. The vestry, a small room used for robing and parish administration, was a standard addition to churches of this type, reflecting the formal organisation of the established church in the years before disestablishment. The 1812 date is recorded by Brady, writing in 1863, which places the church's construction in a period of significant church-building activity across Ireland, much of it driven by the Board of First Fruits, a body that funded the construction and repair of Church of Ireland buildings during the late eighteenth and early nineteenth centuries, though whether Creagh was among its projects the surviving record does not confirm.
