Broich Castle was erected to protect the town from invasion by the Normans 1100 years ago. It is regarded as Mülheim’s oldest building. It is also the oldest, still maintained Carolingian fortification in German-speaking Europe. The halls are now used for municipal receptions and civil ceremonies. In the attic is also the headquarters of the Mülheim City Marketing and Tourism. The Hochschloss is home to the Historical Museum of the Mülheim History Society (open Sa Su 11:00-17:00, as of Dec 2023, free), which provides excavation finds, models and a "Luisen room" insight into several centuries of Mülheim history.
Built in 1893 by famous Thyssen steel company, it's now a museum about water management, part of the Industrial Heritage Route:.
