Phoenix Caisson (outer) is a reinforced concrete structure located off Pagham Harbour in West Sussex, forming part of the Mulberry Harbour defences constructed during the Second World War. The caisson was sunk as a breakwater component in the period following the D-Day landings of 1944, serving as an artificial harbour installation to facilitate the supply of Allied forces in Normandy. The structure represents an important example of wartime engineering and amphibious assault logistics. As a scheduled ancient monument, it survives as archaeological evidence of one of the Second World War's most significant engineering undertakings.
