Gisors Castle

Gisors Castle was a major frontier fortress in the Norman Vexin, the contested border zone between the Duchy of Normandy and the Kingdom of France. Begun in 1097 by William Rufus, its motte-and-bailey core was later enclosed in powerful stone defenses and a great octagonal keep. The castle frequently changed hands during the Plantagenet–Capetian wars.
