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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
