Phoenix Caisson (inner) off Pagham is a Second World War artificial harbour structure, part of the Mulberry Harbour complex constructed for the D-Day landings in 1944. The caisson is a large prefabricated concrete unit designed to be towed across the English Channel and sunk in position to form a breakwater and protective harbour for the invasion fleet. Located off the Sussex coast near Pagham, it represents a significant example of wartime engineering innovation and amphibious assault logistics. The structure remains partially submerged in its original position, serving as an archaeological record of Operation Overlord's maritime infrastructure.
