There has been a church dedicated to St. Etienne (Saint Stephen) in Chinon since the 11th century but the current church was constructed between 1460 and 1490. It comprises a nave of five bays, two side chapels, a choir of two bays and a polygonal apse.
The flamboyant gothic influence is in evidence from the moment you step through the elaborate portal. The stained glass windows are by the master glass-maker Julien-Leopold Lobin who's workshops provided many of the windows for the 19th century church-building programme in the region.
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.
