The original square form castle in Ivry-la-Bataille was built around 960 AD. It was 32x25m wide stone building with a small chapel. Today the first floor of this castle remains and it is the oldest medieval building in Normandy. The castle was enlarged during the next centuries. In the Hundred Years' War it was conquered by English (1418), but moved back to the hands of French (1424). After 1449 the castle was left to decay. The restoration began in 1968.
