The Château d'Ivry-la-Bataille is a ruinous Norman castle in the town of Ivry-la-Bataille in the Normandy region. It is among the earliest examples of a stone donjon or keep, which would become a common feature of later Norman castles in various parts of Europe.
The construction of the donjon dates to around AD 1000;[1] it was constructed by an architect named Lanfred (or Lansfred, Lanfrai)[2] under the orders of Count Rodulf of Ivry (French: Raoul d'Ivry). According to Orderic Vitalis, Rudolf's wife, Aubrey or Aubrée, is said to have had the architect beheaded, so that he couldn't build a similar castle for another warlord.[1]
The donjon has marked similarities with later Norman castle keeps, in Normandy notably Avranches, and in England notably Colchester Castle and the White Tower at the Tower of London; it has been suggested that Ivry was the model for these buildings.[3]
The castle was reconstructed several times up to the 15th century and was repaired by Philibert de l'Orme in 1553.[2] Only ruins now remain, but form an attractive walk overlooking the valley of the river Eure. It is an official historical monument of France (MHC).[4]
