Château de Brousse is large medieval fortress. It belonged to the Arpajon noble family from 1204 until 1700. The first known owners were counts of Rouergue in the 10th century.
Today the castle is open to visitors. Among the beautiful fortifications there is a landscaped rose garden and an prehistoric megalith dating from around 3rd millenium BC.
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.
