The Basilica of Saint-Martin d'Ainay is a Romanesque church in the historic centre of Lyon. Legendary origins of a remarkably large church, which may once have stood on this site, are noted by Gregory of Tours.
A Benedictine priory was founded on the Lyon peninsula in 859. When later it was raised to the rank of an abbey, major building works began: the abbey church was built at the end of the 11th century under Abbot Gaucerand, consecrated in 1107 and dedicated to Saint Martin of Tours. This church is today one of the Romanesque churches still extant in Lyon. The tiny building with its massive walls, watchtower, narrow window openings and spaces for heavy doors, was apparently built with defence in mind, and reflects the many dangers of warfare and violent incursions of the period of its construction.
During the Renaissance the monastery owned a port, the abbot lived in a palace and the monks had the use of substantial buildings, cloisters, a garden and a vineyard. Little by little, the life of the community ceased to be a monastic one, particularly once the abbots became commendatory and were nominated by the king. The abbey's temporal power continued, but its spiritual life evaporated.
In 1562, during the French Wars of Religion, the troops of the Baron des Adrets destroyed part of the buildings, including the cloister; the church was badly damaged. By the end of the 17th century the monastic community had ceased to exist. The church and remaining buildings were handed over to a secular chapter in 1685. The church became a parish church.
During the French Revolution the premises were confiscated and nationalised, and the abbots' palace destroyed. The church became a grain store, which saved it from being likewise destroyed. The church was returned to parish use in 1802. During the course of the 19th century was restored in a Romanesque Revival style by the architects Pollet and Benoôt, destroying the last remains of the cloister and enlarging it by the addition of side chapels.
The basilica at Ainay contains several architectural styles: the chapel of Saint Blandina is pre-Romanesque; the principal structure is Romanesque; the chapel of Saint Michael is Gothic; and the overall restoration and enlargement of the 19th century is Romanesque Revival.
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).
