Grand Bé is a tidal island located few hundred metres from the walls of Saint-Malo. At low tide the island can be reached on foot from the nearby Bon-Secours beach. Around 1360, hermits built a chapel dedicated to Our Lady of the Laurel, then to St Ouen. A redoubt was built in 1555, then replaced by other fortifications in 1652. François-René de Chateaubriand, a French writer native to Saint-Malo, is buried on the island, in a grave facing the sea. Twenty years before his death, he had expressed his desire to be buried on this piece of land facing the sea in order to continue his conversation with the sea.
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.
