POST NORMAN PERIOD

The remains of three other churches from this period are to be found in Bonane. The earliest, Faill a Shéipéil, at Gearhabuí is now a mere outline. The next, Sheana-Shéipéil, the ruins of which are still clearly visible near Bunane Bridge, was in use until about 1840. It was described in 1839, by the then Parish Priest, Michael Enright as one "with tottering walls…wretchedly confined unsafe cabin".

Shortly thereafter a new church was constructed at Milleens, on the site where the present church stands. One wall of this church is still well preserved. It was a relatively low structure with the Sanctuary at the northern end, which is opposite to the arrangement in the present day Saint Fiachna's Church

The present church dates from 1892 and is built of local stone. The nearby Presbytery was completed two years later. Prior to its construction the priests of the parish resided at Releagh. The residence there was built for the engineer in charge of the construction of the New Line road through the Tunnels to Glengarriff.
