There was a church in Carrigaline in the 7th century whose monks (it is believed) were linked to St Finbarr's Monastery in Cork. This church is gone but it is remembered by the location named Kilnagleary or Cill na gClearach which means the Church of the Clerics. Subsequently another church was built in the 1700s, called "The Chapel of St John the Baptist" and this was located on the aptly named, Church Hill. Finally in 1957, the Church of Our Lady & St John opened and has welcomed a strong congregation ever since. The church is very beautiful with some very lovely windows. It has three extremely committed & dedicated priests who are actively supported by parishioners. The church has a wide range of choirs and when Mass from this church was aired on RTE a few years ago, members of these choirs combined to sing for the Mass. There is an Aifreann Gaeilge every month here and appropriately, there is a Cór Gaeilge (Irish choir) who sing at this Mass. Additionally, as the church is located opposite an excellent hotel, it is a popular choice for weddings.
