Château d'Ivry-la-Bataille

Château d'Ivry-la-Bataille is a ruinous Norman castle in the town of Ivry-la-Bataille in the Upper 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 1000 AD, and was built by an architect named Lanfred, Lansfred or Lanfrai, under the orders of Count Rodulf of Ivry (French: Raoul d'Ivry). 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. The donjon has marked similarities with later Norman castle keeps 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.

The castle was reconstructed several times up to the 15th century and was repaired by Philibert de l'Orme in 1553. 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).
