Notre-Dame-des-Marais in La Ferté-Bernard is a jewel of the flamboyant Gothic style, built on drained marshes between the 14th and 17th centruries. Remarkable as much by its Gothic and Renaissance architecture as by its stained glass windows (late 15th, 16th and 19th century), it also has a 'swallow's nest' organ (1536) and a 15th century alabaster treasure.
Church oriented with a Latin cross plan and Gothic style. Although the western gable façade is very sober, the rest of the exterior decoration of the building is in the flamboyant Gothic style. Inside, the church is bright and the filling of its stained-glass windows reveals skilful late Gothic forms.
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.
