Religion
The Roman Catholic Archbishop of the city holds the title "Primate of the Gauls" (Primat des Gaules) and is the leading Archbishop of France. The archdiocese dates to Roman times before Franks entered modern France (see history above).
A mediaeval Pope's admiration of the red vestments of the canons of Lyon is said to have given rise to red becoming the signature color of the cardinals.
Twinning
Lyon is twinned with Birmingham, England.
