When we visited the D-day sites at Arromanches we walked the beach and saw there the remains of the artificial harbors used bring in supplies. These harbors were code-named "Mulberries" and were later destroyed by a storm. The remains of one of them are on the beach and out at sea at Arromanches. The photo shows one of the caissons, which were towed across the English Channel on D-day, and which is now on the beach, and another out in the water off the beach. The inset shows the aftermath of a lunch of mussels enjoyed at La Baraka in Arromanches.
