In 1917, a local excavation of the church interior turned up the remains of 108 skeletons, lying roughly eighteen inches below the surface. The bones were not left where they were found. They were removed and re-interred at St. Brochan's church in nearby Bracknagh, the parish church that still serves the area today.

The church at Ballinowlart was built from rubble limestone with dressed quoin stones, the latter being the cut and shaped corner blocks that give a structure its structural integrity and a degree of finish. The building is now poorly preserved, its form still legible but the fabric considerably degraded. What the 1917 excavation cannot tell us with certainty is who those 108 people were, when they died, or why they were buried inside the church rather than in a surrounding graveyard. Burial within a church interior was typically reserved for clergy or persons of social standing, though mass burial events such as famine or plague sometimes produced less ordered arrangements. The scholar Milner, writing in 1964, documented the excavation in some detail, but the circumstances that brought so many individuals to rest beneath that floor remain unresolved.

The site sits in a landscape that has been shaped as much by its bog as by its farmland, and the ruins are modest enough that they require some attention to locate and read properly. The re-interred remains at St. Brochan's in Bracknagh represent the only physical continuation of whatever community once gathered at Ballinowlart, a small displacement that links two sites across a century of quiet effort to account for the dead.
