Origin and history

The cathedral group of Lyons, made up of the primatiale Saint-Jean, the church Saint-Étienne and the church Sainte-Croix, finds its origins in late antiquity. At that time, each city had only one church, called ecclesia, where the Christian community gathered around its bishop. The first mention of a church in Lyon dates back to 380, mentioned in the Lives of Bishop Saint Just, who describes a place of worship where a man had found refuge. In 469, Sidon Apollinaire, in a letter, described a new cathedral built by Bishop Patiens, without specifying its exact location, but evoking a place close to the Saône ("On one side the road resonates, on the other the Saône echoes").

Archaeological excavations of the 1930s and 1970s revealed, under the present Saint John primatial, a complex of the fifth or sixth century including a church, a Baptistery and adjoining rooms. These findings confirm that this site corresponds to the ecclesia described by Sidon Apollinaire, excluding competing assumptions such as Saint-Nizier or Saint-Irénée. In the Merovingian period, the group was already double (a maxima ecclesia and a Baptistery), then triple in the Carolingian era with the addition of a third church, future Saint Croix. Lyon was the only cathedral in France to have remained multiple until the French Revolution.

The episcopal group experienced historical tensions, notably between the archbishop's power in Saint John and that of the bourgeoisie in Saint Nizier, the latter claiming the title of "primitive cathedral" because of the tombs of bishops it housed, such as that of Saint Just. The Saint-Étienne and Sainte-Croix churches, destroyed during the Revolution, left room for an archaeological park where their remains, exhumed in the 1970s, are now visible. Saint John's primatia, the only surviving, perpetuates this exceptional heritage.

Ranked Historic Monument in 1986, the episcopal group illustrates Lyon's architectural and religious evolution, from its Christian beginnings under the Roman Empire to its medieval configuration. The excavations also highlighted rare elements, such as a Merovingian Baptistery, demonstrating the importance of the site as a spiritual and political centre from the early Middle Ages. Today, the site combines visible heritage (Saint John) and archaeological traces, offering a dive into nearly 1,500 years of Lyon history.
