Château de La Brigue was built by the Ventimiglia family between 1376-1379. In 1543 small bastions were added to the main building. An earthquake partially destroyed the castle in 1546, but it was used to resist a Genoese attack in 1625. The castle was set on fire by the French troops during the French revolution in 1794 and since it has been lying in ruins.
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.
