Primate of Normandy (French: Primat de Normandie) is a Catholic title borne by the Metropolitan Archbishop of Rouen.
[1] The evangelization happened chiefly in major provincial cities.
During that crucial period in history, when Christianity spread throughout Europe, Rouen (la: Rothomagus) was the capital of the Secunda Provincia Lugdunensis.
[2] Pope Callixtus III, by bulls dating from 22 May 1457 and 11 July 1458, reaffirmed the Archbishop of Rouen as Primate of Normandy.
The jurisdiction extends over a land roughly corresponding to the borders of the former Secunda Provincia Lugdunensis to this day.
