Christianity in Besançon
Christianity in Besançon appeared in the 3rd century, a period during which, according to tradition, the martyrs Ferrutio and Ferreolus evangelized the city and its region. However, the torture and assassination of these two figures of Franc-Comtois Christianity are today considered by some historians as an invention of late antiquity, with the former Sequania Gallo-Roman gradually converting to Christianity only from the 4th century onwards.
