What's left of this ancient structure now shares its space rather unceremoniously with modern industrial buildings; a factory shed's gable wall sits almost flush against the church ruins, whilst another shed crowds in from the south side. It's the kind of architectural jumble that tells its own story about how Ireland's past and present collide in the most unexpected ways.

The church itself, catalogued as DG096-019 in archaeological records, appears to date from the medieval period, though its exact age remains uncertain. During the 1890s, excavation work near the church uncovered a significant quantity of human bones, strongly suggesting this was once the site of a graveyard that has since vanished from view. These burial grounds, designated DG096-019001 by archaeologists, have left no visible trace above ground, their existence now preserved only in historical records and the occasional discovery of skeletal remains.

The site forms part of County Donegal's rich archaeological landscape, which spans from Mesolithic settlements through to 17th century structures. Whilst the church at Teelin Bay may lack the grandeur of better preserved ecclesiastical sites, it offers a glimpse into the religious life of a small coastal community. The proximity to the pier suggests this may have served the spiritual needs of local fishing families, providing both a place of worship and, evidently, a final resting place for generations of parishioners whose graves have since been lost to time and development.
