The Château de Mirabeau is a medieval castle overlooking the village of Mirabeau. Its origins date back to the 12th century, when it was first mentioned as a fortified structure. Initially owned by the Abbey of Saint-André, the castle underwent various changes over the centuries. The castle played a crucial role in the local economy, especially during the late Middle Ages, by controlling a key river crossing.
The current structure, likely built in the late 16th to early 17th century, features a quadrilateral layout with four circular towers. It has been remodeled and expanded, particularly in the 18th century, and includes a chapel and various living quarters.
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.
