The castrum in Castiglione delle Stiviere was founded probably in the 9th century, but it is much altered and restored, especially by the Gonzaga family of Mantua in the 16th century. The castle was home to a cadet branch of the House of Gonzaga, headed by the Marquis of Castiglione. Saint Aloysius Gonzaga (1568–1591) was born there as heir to the marquisate, but became a Jesuit. He died tending plague victims in Rome and was buried there, but his head was later translated to the basilica in Castiglione which bears his name.
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.
