The Church of Saint-Nizier name refers to Nicetius of Lyon, a bishop of the city during the 6th century. The first religious building on the site of the present church was a Roman monument, perhaps a temple of Attis, whose worship was probably the cause of the Christian persecution in Lyon from 177. In the 5th century, according to tradition, Eucherius of Lyon, 19th bishop of Lyon, built on the ruins of the building a basilica to contain the relics of the martyrs in Lyon, tortured in 177. In the 6th century, the bishops were buried in the church, particularly Nicetius of Lyon, the 28th bishop. The body of the latter attracted a crowd and his presumed great miracles led the church to take his name.
In the early 8th century, the church has been ravaged by the Saracens and by Charles Martel. It was rebuilt in the 9th century, at the behest of the bishop Leidrade. Peter Waldo, in the 13th century, was a parishioner. His disciples, shocked by the wealth of the church, even set fire in 1253.
From the 14th century to the late 16th century, the church was gradually rebuilt. In 1562, the notables gathered in the church, and in the 17th century, the aldermen were elected in the nave. It suffered the damage caused by several bands of Huguenot, which plundered the bishops of Lyon's tombs, then those of the French Revolution.
After the French Revolution, the church served as flour warehouse. In the late 18th century, the project to transform the church into a gallery was abandoned after a petition signed by 100 notables.
The sacristy was built in 1816, and the organ was installed in 1886.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
