Château d'Ivry-la-Bataille is a ruined Norman castle situated on a strategic promontory overlooking the Eure valley in Normandy, France. Dating to around AD 1000, it features one of the earliest stone keeps in Normandy, built under the direction of Count Rodulf of Ivry. Its fortified position between the Duchy of Normandy and the Kingdom of France made it a contested stronghold through medieval conflicts. The castle's architectural innovations influenced later Norman fortifications, including reportedly serving as a model for the Tower of London. Following excavations from 1967-1982, the ruins have been cleared and presented as a historical site, showcasing the evolution of medieval military architecture.
