Not a bell tower, not a decorative feature, but a chimney, the kind of thing you would expect to find on a dwelling rather than a place of worship. The wall runs east to west, measures about four metres long and three and a half metres high, and sits within an irregularly shaped modern graveyard on a gentle north-facing slope overlooking boggy ground. No architectural details survive to help identify what the building originally was, how old it might have been, or what form it took.

The chimney detail surfaces in the Ordnance Survey Letters, a remarkable nineteenth-century archive in which antiquarians were sent across Ireland to record local history and topography ahead of the first detailed mapping of the country. In the volume compiled by O'Flanagan, published in 1927, the entry for this spot reads plainly: "In Killosolan church yard there stands the gable of some edifice, with a chimney on it." The careful phrasing, "some edifice", suggests the writer was already uncertain what he was looking at. Whether the chimney served a residential function incorporated into the church building, indicated a later adaptation of the structure for secular use, or pointed to something else entirely, the record does not say. The chimney itself is no longer visible.

What remains, then, is a wall that raises more questions than it answers, standing in a graveyard that has continued in use long after the building it once belonged to fell away around it.
