Beneath the chancel floor lies a vault belonging to the noble family of Desart, and somewhere to the south of the building a human figure carved in stone may mark an effigial tomb, the kind of recumbent carved memorial that was once a common way of commemorating the distinguished dead. The chancel retains its roof, alone among the ruins, partly because of what it contains.

The site's layers go back further than the standing structure suggests. The old Catholic parish church here was dedicated to St. David, Bishop, whose feast falls on the first of March, and was known as the Church of Inchiologhan. According to the historian Carrigan, writing in 1905, that earlier building was taken down to the ground more than two centuries before his time, and the Protestant church raised in its place. By 1839, Ordnance Survey correspondents were describing it as a modern Protestant church with an associated burial ground. It did not remain in use for long after that: when the Irish Church Act of 1869 disestablished the Church of Ireland, ending state support and reorganising its parishes, services here were discontinued and the roof was stripped away, with the exception of the chancel above the Desart vault. A wall monument still survives on the north wall of the chancel. Hogan, visiting sometime between 1880 and 1883, found the building already well on its way to ruin, describing it as a venerable old structure shrouded by ivy.
