Dating back to at least the early 17th century, the church was already in ruins by 1622 according to the Royal Commission records. Following repairs or rebuilding, it served the local community for another two centuries until 1829, when a new church was constructed at Ballydevitt, finally ending Killymard’s long tenure as the parish’s spiritual centre.

Today, visitors to the site will find atmospheric remains measuring 12.5 metres by 5.5 metres internally, built from rubble stone construction. The western gable wall stands nearly at its original height and preserves fascinating architectural details, including the remnants of a bell-cote and what appears to be a flue-like shaft, likely designed to accommodate a bell-rope. Whilst the central doorway has been reduced to a ragged gap with some facing stones, traces of both interior plaster and exterior rendering hint at the church’s former appearance. The north and south walls survive to varying heights; 2.3 metres and 1.5 metres respectively, though portions have been removed over time to make way for burial plots.

The church sits within a graveyard containing modern grave slabs, with the earliest recorded dating from 1809, suggesting continued use of the burial ground even before the church was finally abandoned. An intriguing connection to the site’s past exists in the form of a carved stone head, believed to depict a bishop, now housed in Ballydevitt Church. Local tradition holds that this head, along with a second one now lost, once adorned the gateposts of Killymard’s graveyard, serving as stone sentinels watching over the departed.
