Fort Gorazda was built by the Austro-Hungarian Empire near Kotor. The fortress's predecessor was built prior to the 1869 uprising. The current fort was built between 1884–86 and replaced an earlier structure; its most notable feature is a 100-ton Gruson rotating turret on its roof, the last remaining example of its type. The fort was used by the Austrians in artillery duels against Montenegrin batteries stationed on Mount Lovćen during the First World War. The Montenegrins were unable to destroy it and were pushed out of range in 1916 by an Austrian offensive. The damage to the fort was repaired and its guns were removed to support the Austrian field army. It was used as a depot by the Yugoslav Army until as recently as the early 1990s. It was subsequently abandoned and can be visited by the public.
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.
