Saint Germain castle in Montjovet played an important part in the history of Val d’Aosta. Few traces remain of its original structure and its construction date is not known for certain. At the end of the 13th century, the Savoy became the owners, replacing the Montjovet family. As already happened in Bard, in this case too, the pretext was provided by the abuse of power that Feidino Montjovet acted on villagers and wayfarers. The castle was later sold to the Challant family but returned to the Savoy in 1438, when Amadeus VII installed a garrison there, which remained active until 1661, when it was transferred to the fortress in Bard, leaving Montjovet castle open to decay.
References: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.
