Condé-sur-Noireau is a commune in the Calvados department in the Basse-Normandie region in northwestern France. It is situated on the Noireau River. In the fifteenth century, the town was occupied by the English, and belonged to Sir John Fastolf of Caister Castle in Norfolk (1380-1459). It was from here that the Spanish mercenary Francois de Surienne launched an attack on Fougeres in Brittany, which triggered the invasion of English Normandy by Charles VII of France, and the end of the Hundred Years' War.
