Known locally as Clocmakeeran Church, the site sits at the centre of an early ecclesiastical enclosure, the kind of roughly circular boundary that often marks a Christian foundation of considerable age, predating the more regular planned layouts of later medieval parishes.

When the antiquary Neary recorded the site in 1914, the church was already a ruin but still legible. He could trace the full outline of a building measuring approximately 21 metres east to west and nearly 8 metres north to south, with walls around 0.9 metres thick. A cross wall some 7.3 metres from the eastern end appeared to divide the nave from the chancel, the two main compartments of a standard medieval church plan, the nave being the congregational space and the chancel the liturgical east end reserved for the altar. By the time of more recent survey, that entire western portion had vanished below ground. What survives is only the outline of the chancel, a small rectangular structure roughly 4.5 by 6.2 metres, with a single stretch of north wall still standing to a height of 1.4 metres. The traces of the dividing wall at the western end of even this remnant are about all that physically echoes Neary's earlier description.

The window fragment is the one piece of worked stone to survive. Tracery, the decorative stonework that fills the upper portion of a Gothic window and subdivides it into geometric or flowing forms, implies a building of some ambition, even if the scale was modest. Lying displaced outside the south wall rather than in situ, it offers a small and slightly melancholy reminder that this was once a dressed and finished piece of architecture, not merely a functional enclosure of rubble.
