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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
