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:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
