The first castle of Châteaugiron was built in the middle of the 11th century by Anquetil, a Norman knight, who had received the lands from Alan III, Duke of Brittany. The oldest part of the current castle is the castle's Romanesque chapel dating from the 12th century. Probably in the 13th century, Châteaugiron castle was rebuilt as a stone fortress. Currently the Château de Châteaugiron fulfills several functions; its main body is used as a town hall, the other parts are used as offices and the independent keep is used for exhibitions.
