What survives of this ruined medieval church in County Kildare tells a quietly complicated story, one written not in documents but in blocked windows, mismatched masonry, and a chancel arch that can only have been inserted after the building it connects was already standing. The west end of the nave has collapsed entirely, ivy has taken hold of much of what remains, and the interior is shared between 18th and 19th-century headstones and loose piles of fallen stone. Yet enough is intact to reward a careful look.

Scholars have identified three distinct building phases here, each leaving its mark on the fabric. The oldest part is thought to be an 11th-century single-cell structure, roughly 8.3 metres long, built from coursed and dressed limestone. In the 12th century, when the site was held by the diocese of Glendalough, a chancel was added to the eastern end, effectively converting the original cell into a nave. The chancel, a smaller and more crudely built compartment measuring about 5 by 3 metres internally, was not bonded to the nave wall, meaning it was constructed as a distinct addition rather than as part of a unified build. To connect the two spaces, a round-headed chancel arch was inserted, spanning roughly 2 metres in width and springing from rectangular abacuses, the flat projecting blocks that cap the responds. Inserting this arch required blocking a window that had previously occupied the east gable of the nave, a detail that fixes the sequence clearly. A third phase, probably in the 15th century, saw the nave extended westward, bringing its internal length to around 14.5 metres. The windows throughout are narrow and varied in type: one in the south wall of the nave has a tympanum-stone fitted beneath a round arch to create a square-headed opening, a practical solution that appears more than once in the building.

The ruin sits at the northern end of a graveyard, within what may be the remains of an associated field system. The graveyard itself remained in use into the modern period, as the headstones inside the nave confirm, so this is a place where centuries of activity overlap in a relatively small area of ground.
