Arromanches-les-Bains (French pronunciation: [aʁɔmɑ̃ʃ le bɛ̃] ⓘ; or simply Arromanches) is a commune in the Calvados department in the Normandy region of north-western France.

[citation needed] 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.

One of these ports was assembled at Arromanches and even today sections of the Mulberry harbour still remain with huge concrete blocks sitting on the sand and more can be seen further out at sea.

Situated in a good location for visiting all of the battle sites and war cemeteries, there is also a museum at Arromanches with information about Operation Overlord and in particular, the Mulberry harbours.

It was a temporary sculpture project—a visual representation of 9,000 people drawn in the sand which equates the number of civilians, German forces and Allies that died during the D-day landings.
