The Artificial Port of Arromanches
Elements of the port were prefabricated in England, towed across the Channel and installed off the coast at Arromanches to form a second artificial harbor, similar to the port at Saint-Laurent-sur-Mer. It was the beginning of the installation of Mulberry “B” also named “Port Winston” after British Prime Minister, Winston Churchill, who had the idea of constructing the harbours. In addition to the caissons, 17 block ships were sunk to reinforce the concrete structures. Mulberry “A”, at Saint-Laurent was reserved for the American forces and Mulberry “B” for the British. This division existed until the devastating storm of 19th-22nd June which completely destroyed the American port leaving Arromanches as the only Allied artificial harbor operational during the Battle of Normandy.
