The Château des Rohan is a former castle and weapons factory now serving as a museum and cultural centre in the French town of Mutzig. The castle's history goes back to the fortification of the town in 1274 by Rudolph of Habsburg. The medieval castle was heavily destroyed by the Swedes in 1632, during the Thirty Years' War, after having already been assaulted by Ernst von Mansfeld's troops in 1622. The city's and castle's masters, during these times marked by frequent battles and rivalries between feudal families, were alternatively and sometimes simultaneously the bishops of Strasbourg and the House of Zweibrücken.
The castle as it now appears is a Baroque structure. It was inaugurated in its present shape in 1673 to serve as the residence of the bishop of Strasbourg, Franz Egon of Fürstenberg. Fürstenberg was succeeded by his brother Wilhelm Egon von Fürstenberg. After the family of Rohan took over the bishopric of Strasbourg, the castle served as a residence to the dukes Armand Gaston, François-Armand, Louis Constantin and Louis René Édouard de Rohan, between 1704 and 1790.
However, after the completion of the Palais Rohan of Strasbourg in 1742, the château, which had already been rivalled by the residences in Saverne, became only of secondary importance to the family. Mutzig's castle was disowned and pillaged during the French Revolution. In 1799, it was bought by the arms manufacturers, brothers Coulaux of Klingenthal who in 1801 opened their weapons factory in its walls.
The factory ran until the outbreak of the Franco-Prussian War in 1870. The castle was fortified again by the Germans in 1893. Today, the castle houses a cinema and a library as well as, since 1996, the municipal museum Musée régional d'armes displaying a vast collection of historic rifles.
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.
