The Leper’s Tower was built on the ruins of an ancient Roman tower and was originally known as the Friour Tower, after the family that lived there. This family, whose name was mentioned for the first time in 1191, also occupied the Ports Decumana, now abandoned.
After several changes of ownership, it was bought by the Order of Saint-Maurice in 1773 and was incorporated into a hospice of charity founded by Jean-Boniface Festaz. The current name derives from the fact that a leper named Pierre Bernard Guasco, a native of Oneglia was imprisoned there from 1773 to 1803. This story inspired Lepers of the city of Aosta, a story written by Xavier de Maistre, published in 1811.
In 1890, the tower was restored. Today it belongs to the Autonomous Region of Aosta Valley, which holds exhibitions at the site.
The Leper’s Tower was founded on a Roman tower whose foundations were excavated in the nineteenth century. A medieval tower was built on the site in the 15th century.
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.
