Château de Fleury-la-Forêt is an impressive red-brick castle built in 1595 by Pierre de Courcol. It was partially destroyed by fire in 1643, but restored by Charles de Caumont later. The new chapel was founded in 1658. The two wings were added during the next restoration in 1700. Today Château de Fleury-la-Forêt is a hotel.
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.
