They almost certainly once supported a loft, suggesting that at some point this modest rectangular building had a more complex interior life than its rough sandstone rubble construction might imply. The church measures around 17 metres east to west and just over 8 metres north to south, and despite being heavily overgrown and in poor structural condition, enough survives to make out the careful detailing of its better moments: chamfered sandstone surrounds on the twin-light east window, an ogee-headed light in the south wall (the ogee being a shallow S-curved arch associated with late medieval craftsmanship), and a doorway with cut-sandstone chamfering, now largely collapsed.

The parish church of Macroney has a recorded history stretching back to at least 1291, when it appeared in the Papal Taxation, a Europe-wide survey of church property commissioned by Pope Nicholas IV to fund a crusade. By 1615 it was still reported as being in repair, which places its active life well into the post-medieval period. Sometime between then and 1774, the building fell into the ruin it remains today. The east gable survives to its full height and retains what appears to be a blocked second window, larger than the surviving one and positioned higher in the gable wall; a scholar named Power noted its existence in 1932, though ivy has since obscured the area entirely. The north wall has a two-metre gap directly opposite the main doorway, possibly a deliberate opposing opening, and the west gable still holds a splayed window embrasure about three metres above ground, its light hidden behind vegetation.
