It was on the beach of Arromanches that, during the Invasion of Normandy immediately after D-Day, the Allies established an artificial temporary harbour to allow the unloading of heavy equipment without waiting for the conquest of deep water ports such as Le Havre or Cherbourg. Although at the centre of the Gold Beach landing zone, Arromanches was spared the brunt of the fighting on D-Day so the installation and operation of the port could proceed as quickly as possible without damaging the beach and destroying surrounding lines of communication. The port was commissioned on 14 June 1944.
