The footprint is remarkably small, somewhere in the region of eight metres long and under three metres wide according to one early account, which puts it closer in scale to a domestic room than to a parish church. That smallness is part of what makes it worth attention. Westropp, writing in 1904, described it plainly as a "rude, late little oratory", and the phrase captures something honest about the place.

The parish itself has a documentary history stretching back to at least 1201, when it appears in the record as Killmacgoban. Later spellings accumulate across the medieval centuries, Killagoban in 1296, Kilgubban in 1298, Kilghobain in 1410 and again in 1418, Kilgaban by 1615, each variant a small sign of a community present and functioning around this modest structure. Begley, writing in 1906, noted that the church is frequently mentioned in the Black Book, a term referring to episcopal registers or cartularies kept by dioceses to record property, rights, and obligations, which suggests Kilgobbin held some administrative significance within its diocese even if the physical building never aspired to grandeur. By the time antiquarians came to record it, the parish had already been merged into another, and the stones of the west doorway had been removed entirely, leaving only the outline of where they once sat.

The site is not accompanied by obvious visitor infrastructure, and the remains are modest enough that knowing what you are looking at beforehand makes the visit considerably more rewarding. The west gable is the focal point, the belfry feature above the former doorway being the most legible remnant of the church's original form. Given that the surrounding area is rural County Limerick, access is likely on foot across farmland, and it is worth confirming locally before approaching. The walls that remain are low, and the sense of the place comes not from drama but from the quiet accumulation of its documented names across seven centuries.
