Once situated directly on the banks of the Rhine, Brömserburg Castle was owned by the Archbishops of Mainz from the beginning of the 10th to the beginning of the 19th century. During the 12th century they converted the old fortress into a castle residence. With its vaulted ceilings and walls of more than two metres thick, it successfully provided resistance against any attack. One exception was the destruction of the castle’s southeastern part, which was destroyed in 1640 by the Duke of Longueville. The castle was inhabited up until 1937, before be- ing acquired by Rüdesheim’s town council in 1941. Today, the castle houses the extensive collections of Rheingau’s wine museum.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
