It is not known when the Chapter of Cashel was established, but in 1224 Pope Honorius III confirmed twelve Canons and a Dean in the historic cathedral of St Patrick, located at the Rock of Cashel.
[1] For centuries the Chapter consisted of five dignitaries and six prebendaries, the Archbishop of Cashel being one, holding the prebend of Glankeen as parcel of his see.
[1] Following the Reformation, the Church of Ireland retained the cathedral until it was closed for worship in 1721.
[2] Meanwhile, the old parish Church of St John in Cashel was removed and the present Georgian Cathedral completed in 1784.
[2] The most recent dean, the Very Reverend Gerald G. Field, was instituted and installed in February 2014.
