Mulberry Harbour - Arromanches-les-Bains-Normandie- France: This beach was designed Gold Beach during the D-Day landings, one of the beaches used by British troops in the Allied invasion. Arromanches was selected as one of the sites for two Mulberry Harbours built on the Normandy coast. Sections of the Mulberry Harbour at Arromanches still remain today with huge concrete blocks sitting on the sand.
