What makes this ruined church in County Kildare quietly peculiar is that you cannot walk from one end to the other. The nave and chancel of this medieval limestone structure are physically cut off from each other, divided by a brick-built family vault that was inserted in the early nineteenth century and has never been removed. The vault belongs to the Hamiltons, and it occupies the chancel arch area so completely that the original passage between the two spaces is entirely blocked. All that survives to suggest there was ever a grand opening between nave and chancel is a step-back in the eastern wall and the base of a column on the south side, the ghost of an arch that no longer exists in any meaningful way.

The building itself is a fairly well-preserved rectangular structure running roughly 21.5 metres east to west, with walls of roughly dressed, randomly coursed limestone rising to near their original height. The nave, the western and larger portion, is lit by a twin-light ogee-headed window in the west gable and by single-light ogee windows at the eastern ends of both the north and south walls. An ogee head is a curved profile combining a concave and convex arc, common in late medieval Irish ecclesiastical architecture. A small niche beside the south doorway almost certainly held a stoup for holy water. The chancel, which was rebuilt at some point, is now entered not from the nave but through a two-centred arched doorway inserted into the east gable wall, a doorway that may originally have come from a nearby castle. It has a fluted surround, hood-moulding, and chamfer-stops, giving it a rather more refined character than the rest of the fabric. Inside the chancel, two small aumbries survive, recessed wall cupboards used in medieval liturgy for storing vessels and sacred objects, one retaining its iron hinges. Fitzgerald, writing in the 1890s, recorded a seventeenth-century tomb in the south-east corner of the church, and the Hamilton vault itself incorporates part of a sixteenth-century altar-tomb. The nave, for its part, holds eighteenth- and nineteenth-century headstones, and at its eastern end there is an overgrown accumulation of broken stone that was once, presumably, commemorating someone.
