From high up on the rock of Susa, this castle has witnessed millennia of history. In 1046, Countess Adelaïde received here her husband Otto, Count of Savoy, bringing him the dowry of the marquisate of Susa and the county of Torino.
The Castle was presumed to be built in the Middle Ages, this also explains the presence of mullioned windows on the walls, a typical element of that era. Over the years he underwent several restorations, especially in the 18th century, which gave him the present appearance. Today, it houses in its interior the Historical Archives, the Civic Museum and the Library.
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.
