Château de Saint-Malo was built between 1424 and 1690, first by Jean V, the Duke of Brittany. The Duke Francois II built the first tower in 1475. In 1590 during the Wars of Religion the castle was occupied by local people, who wanted to prevent local governor to gave the city to Protestant king Henry IV.
The château was modified in the 17th century according the design of famous fortress architect Sebastian Vauban. In the 19th century it functioned as barracks. Today it is a museum, covering a number of themes including the long maritime history of St-Malo, 19th century writers of which Chateaubriand is the most well known, WWII occupation and the destruction and reconstruction of the town.
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.
