In 1837, the town was split between the Church of Ireland parishes of Kilfentinan and Kilfinaghty while the Roman Catholic parish of Sixmilebridge was a union of the Kilmurry-Negaul, Kilfinaghta and Feenagh parishes.

The church of St. Finnachta was built in 1812 in Sixmilebridge, a thatched building with a mud floor.
In 1980 the building was reconstructed and considerably enlarged.
This is the only church in use in the Catholic parish of Sixmilebridge, which is in the Roman Catholic Diocese of Killaloe.

The Little Church, of Cratloe Parish, on the Limerick Road, is part of the Diocese of Limerick.
It is less than 500 metres (1,600 ft) away from St. Finnachta's.

The former Church of Ireland (Anglican) building on Church Street, Kilfinaghty Church, is now used as the local branch of Clare County Library.

Arguably the oldest church in the parish is that of Ballysheen, reputedly built in the 12th century by Saint Finaghta.
It is in a poor state, with two of the four walls still standing.
Its surrounding graveyard is still a popular burial place for people of the parish.

Feenagh church, southwest of Sixmilebridge, is also a very old church.
Feenagh was once a separate parish to Kilfinaghta.
