Cherbourg is a town in Normandy, north-west France, situated at the north of the Cotentin Peninsula. The Cotentin was the first territory conquered. the Vikings. For these sea people, it was logical that Cherbourg should become a port. The city evolved in relation to the Anglo-French conflicts before becoming a Channel stronghold and, in 1944, the world's most important harbour. The Anglo-Norman state created in 1066 after William's victory at Hastings was a decisive factor in the development of Cherbourg with its exceptional geographic position in the heart of this state. In 1145, William the Conqueror's granddaughter, Matilda, acquired land in the parish of Equeurdreville (La Croûte du Homet) on the approximate site of the modern Cherbourg Arsenal. She ordered the construction of an abbey dedicated to the Holy Virgin, whose cult was in full expansion at the time, the Abbaye du Voeu, of which important remains still stand.
