The Château of the Dukes of Bourbon is a castle in Montluçon, France, largely built by the Dukes of Bourbon.
In 1070, Guillaume, son of Archambaud IV of Bourbon became Seigneur of Montluçon and built a fortress on a castrum.
The English occupied the Castle of Montluçon from 1171 to 1188. After that invasion, Philip Augustus handed it over to the Bourbon family. The latter transformed it into a stronghold.
The remainder of the castle was built starting from 1370, at the heart of the Hundred Years' War, by Louis II, Duke of Bourbon.
