Diocese of Duleek

The Diocese of Duleek was an Irish diocese which remained a separate bishopric at the Synod of Kells held in 1152 but disappeared not long after that date. Firstly subsumed by the Diocese of Meath and now within the Diocese of Meath and Kildare.

It began as an early Christian monastic settlement. St Patrick established the bishopric circa 450 AD.
