To protect the County of Nice from invaders, the Duke of Savoy built the Saint-Elme citadel in the 16th century, together with the satellite fortresses of Mont-Alban and Saint-Hospice, and the port of La Darse where the galleys were moored. These constructions entrusted to Italian engineers were fore-runners of a new type of bastion fortification. Today, this remarkable complex (7.5 acres) accommodates the Town Hall, the Volti, Goetz-Boumeester Museums and the Roux Collection.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
