Kilfane Church, Medieval church ruins in County Kilkenny, Ireland.

Kilfane Church is a medieval ruin in County Kilkenny featuring Gothic stonework and original interior elements. The building contains three doorways with pointed arch stones, an altar, a basin for washing, and recessed areas carved into the walls.

The church was founded in the 13th century and served the Cantwell family, who held power as lords of this territory after the Norman invasion. Their influence lasted until the later upheavals that changed Ireland's religious and political landscape.

The Cantwell Fada is a knight effigy carved in the 1320s or 1330s, meant to lie flat as a tomb cover but now set upright under a transparent cover. When the church served as a schoolhouse, misbehaving children were made to kiss it. Four casts were made, one displayed in the National Museum in Dublin.

Kilfane Church stands about 3.4 km north-northeast of Thomastown, reached by minor roads through Kilfane. The ruined nave and the tower house at the east end are entered through the original north and south doorways. The Cantwell Fada is set upright under a transparent cover, so look for it inside rather than among the graves outside.

The limestone figure once played an unusual role in school life at this site, serving as more than just a religious monument. Children were made to kiss the stone as punishment, revealing how the space transformed over time.
