Known as Templemurry, a name recorded on the 1922 Ordnance Survey map indicating a dedication to the Virgin Mary, the building does not even appear on the earlier 1838 six-inch OS map, suggesting it was already so ruined by that point as to be considered barely worth marking. Today, the east and west gables have collapsed entirely, leaving only sod-covered mounds of stone where they once stood, and the surviving north and south walls are so engulfed by vegetation that little of their structure is readable from the outside. Inside, graveslabs lie buried under the same creeping overgrowth.

The church's documentary history offers a few precise, if fragmentary, glimpses of its medieval life. Papal Letters from 1448 to 1449 describe it as the "perpetual vicarage of Rathfran", a term denoting a parish church served by a vicar rather than a rector, with the income typically going to a larger institution. A further entry from 1455 records the vicar by name: William O'Mochan, who had been excommunicated yet continued to celebrate mass regardless. It is the kind of detail that tends to get smoothed over in broader ecclesiastical histories, but it points to the friction that existed between local clergy and the machinery of Rome even in a small, remote parish on the Atlantic edge of medieval Ireland. Where the building fits in the local landscape of religious architecture is suggested by its modest dimensions, roughly nine metres east to west and five and a half metres north to south, with walls of mortared stone around sixty to seventy centimetres thick. Traces of lime render still cling to the inner faces of both walls, a reminder that the interior was once plastered and finished rather than left as bare rubble. A piscina, the shallow stone basin used by a priest for rinsing sacred vessels during mass, was noted near the east end of the south wall during survey work in the 1980s, its pointed trefoil arch already fallen and lying on the ground; by later visits, even this had vanished from view.
