Quick Summary

Mulberry B was one of two artificial harbors constructed by the British during World War II to aid in unloading supplies after the invasion of Europe on D-Day, June 6, 1944. Located off Arromanches at Gold Beach, it was part of the Allied strategy to overcome German coastal defenses.

The harbor consisted of floating roadways made of steel spans (Whales) supported by pontoons (Beetles), leading to adjustable pierheads (Spuds). These were sheltered by sunken caissons (Phoenixes) and sunken ships (Gooseberries).

While the American sector's harbor was destroyed by a storm, Mulberry B supported Allied forces for ten months, facilitating the landing of millions of troops, vehicles, and tons of supplies. Remains of the structure are still visible today.
