Religion of Lyon

The Roman Catholic Archbishop of the city holds the honorary title “Primate of the Gauls” (Primat des Gaules). The archdiocese dates to Roman times before Franks entered modern France (see history above).

The red vestments of the canons of Lyon are said to have given rise to red becoming the signature color of the cardinals, in a decree promulgated under Pope innocent iV at the First Council of Lyons, 1245.
