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 historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
