Preparations for converting Morsbroich Castle into a Museum of Modern Art began in 1975. At that time, the museum was housed in the main building, a grand bourgeois residence from the late 19th century, which the city of Leverkusen had acquired after the Second World War. The outer bailey, with its stables and coach houses, was only partially used and was largely in a state of disrepair. The museum's program could not be fulfilled within the available space. Therefore, it was necessary to develop a comprehensive plan that incorporated all the buildings and the castle grounds.
