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 Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
