Built by Vauban in 1681 and fortified by Napoleon III, the fortress dominates the city of Villefranche-de-Conflent with its ramparts, counterscarp galleries, bastions, chapel, archaeology and caving museum and a 734 steps underground staircase. The ramparts - major site built by Vauban- are registered on the list of the Unesco World Heritage.
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.
