The Diocese of Pontoise (Latin: Dioecesis Pontisarensis; French: Diocèse de Pontoise) is a Latin Church ecclesiastical territory or diocese of the Catholic Church in France. Erected in 1966, the Diocese of Pontoise was split off from the Diocese of Versailles. The diocese is a suffragan diocese in the ecclesiastical province of the metropolitan Archdiocese of Paris., the diocese had one priest for every 4,488 Catholics.
The first ordinations since its 1966 founding occurred in 2011, when four men were ordained priests for the diocese.[1]
The Church Saint-Maclou became the Diocese of Pontoise's cathedral when the diocese was created in 1966. Exceptionally among French Catholic dioceses, Pontoise owns its own cathedral. Many cathedrals in the country are owned by the French state.[2]
