Broich Castle was originally erected to protect the town of Mülheim from invasion by the the Normans in the late 9th century. It is probably the oldest, still maintained Carolingian fortification in German-speaking Europe.
The abandoned castle was rebuilt and expanded by the noblemen of Broich in the end of the 11th century. The castle survived a long and eventful history, including bloody feuds, wars, occupation and destruction.
Over 200 years ago, Broich’s most famous guest stayed there - Luise, Queen of Prussia - as the castle was owned by her grandmother.
Today, an exhibition of the local society for history informs the visitor about these events and explains their meaning for the city Mülheim an der Ruhr. It is also a popular location for weddings, music festivals and other events.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
