Located in the eastern Pyrenees at an altitude of 1600 metres, the stronghold of Mont-Louis was built from scratch by Vauban on granite terrain and is perfectly adapted to the geography of the site. Work started in 1679 and was completed in two years. The fortified ensemble was added as a complement to Villefranche-de-Conflent in securing the route from the Pyrenees.
This ensemble consists of two square structures, in tiers on the slope: a citadel with orillon bastions and demi-lunes (ravelins) and a new town enclosed in the enceinte. Although it is rare, all the watch towers and drawbridge gates as well as both churches and wells have been preserved intact since the 17th century. The citadel is still used for military purposes today.
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.
