Mazzè Castle castle belonged to the Valperga family for seven centuries, until its extinction in 1840. Originally built to the site of ancient Roman fort, it has been renovated and modified several times across the centuries. In particular, it is important to mention the renovation works performed under the direction of architect Velati Bellini in the 19th century, which gave the castle its current appearance.
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.
