[2] Built around 549 by the Lyon bishop Saint Sacerdos, the church was damaged in 732, then restored in the early 9th century by archbishop Leidrade.

Many changes were made to the church during the 19th century, including the removal of saltpetre soil and the paving, along with numerous additions: the lantern of the top of the octagonal tower in 1835, the Gothic portal in 1877, paintings by Paul Borel added to the choir in 1899, the eleven bells of the bell tower, and so forth.

The current 24-meter stone spire which tops the tower disappeared in 1818, was replaced by another one in wood in 1875, and was finally rebuilt in 1982.

[4] A gallery in quatrefoils, a rose window and shields compose 19th century western facade.

The lower bell weighs over four tons was cast in Lyon by Gédéon Morel and is the most decorated one in the world.
