The church is situated on a hillock within the town but has been abandoned since the late 19th century and is severely neglected.
He appears to belong to the early historic era of Ireland; the Annals of the Four Masters noted the death of Ailbhe of Ceann Mhara in the year 814, so the presumption is that a church was already built, and dedicated, by the early 9th century.
The Voyage of the Uí Chorra, dated to about the 11th century, describes the destruction of the church of the holy old man Coman of Kinvara.
It has been suggested that Coman should be identified with Colman MacDuagh or Caimin of Inis Cealtra.
Both were related to Guaire Aidne mac Colmáin whose fort of Dunguaire Castle is located some hundreds of yards away.
