Origin and history

The Saint-Irénée church, located in the 5th arrondissement of Lyon, is an emblematic monument mixing architectural elements from several epochs. Its crypt, dating from the 9th century, is one of the oldest in France and dates back to the Carolingian era. The present church, rebuilt in the early 19th century and completed in 1830, replaces an older building destroyed during the Wars of Religion. It was classified as a historical monument in 1862, while its calvary and cross path, erected between the 18th and 19th centuries, were registered in 2021.

The site is based on an ancient Roman necropolis active from the High Empire to the Middle Ages, as evidenced by archaeological excavations carried out since the 19th century. Roman and Paleo-Christian sarcophagus, including the famous sarcophagus of the Triomphe of Bacchus (now at the Lugdunum Museum), were exhumed. The crypt houses the relics of Saint Irenaeus, as well as those of the Lyonian martyrs Alexander and Epipode, mentioned by Gregory of Tours from the 5th century. The church, devastated in 1562 by the Protestants, was restored from 1584 and then turned into a fenil during the Revolution before its reconstruction in the 19th century.

The crypt, partially preserved since the fifth century, presents paleo-Christian frescoes and a mosaic destroyed in 1562, a text of which evoked two temples founded by Saint Patians. The Calvary, erected in 1687 and rebuilt in the 19th century, dominates the Saône and offers an exceptional view of Lyon. It comprises fourteen terracotta stations, two of which frame the Crucifixion scene, and an underground chapel representing the Holy Sepulchre. Recent excavations (2022-2024) revealed walls of the choir dating from the 7th century and frescoes of the 18th century.

The current neoclassical church, with Byzantine influences, houses 19th and 20th century stained glass windows illustrating the Lyon martyrs, as well as an 1855 organ restored in 2018. Accelerated to a chapel of Byzantine rite since 1991, it remains an active place of worship. The Calvary, the final point of an old urban cross road from the Church of St. Croix, is one of the few examples preserved in urban areas.

Archaeological excavations have confirmed the importance of the site, occupied without interruption since ancient times. The crypt, restored in the 19th century, retains elements of the 5th century, while the access corridors date back to the High Middle Ages. In 2024, research was under way to locate the relics of Saint Irenaeus. The monument thus illustrates nearly two millennia of Lyon religious and funeral history.
