In 1927, which is quite recent, the town "Borgo San Donnino" changed its name to "Fidenza" as it was known as "Fidentia Julia" in Roman times.

The city was given its name and the Duomo within the walls was dedicated to San Donnino di Fidenza (aka 'Donninus of Fidenza'), who was martyred nearby in 291. A legend tells, that when Charlemagne passed through "Borgo San Donnino", an angel told him, where to dig for San Donnino´s relics. He is connected to the city and the duomo.

Sigeric the Serious, Archbishop of Canterbury, made a pilgrimage to Rome on the Via Francigena around 990. His contemporary accounts of this voyage still exist (and are the source of modern guidebooks). He reached "Sce Domnine" after 36 days, which is pretty fast for 1000+ km.

Frederick Barbarossa had entrusted "Borgo San Donnino" to the Pallavicino family from Piacenza. In 1268, after a siege, the city was conquered by the troops of Parma, who plundered and burned it completely. All houses were destroyed at that time, only the unfinished Duomo was saved.
