The Second World War extension of the Tower Hill Memorial, designed by Sir Edward Maufe, takes the form of a semi-circular sunken garden located behind the First World War Memorial. At the south side of the garden are two columns with statues representing an officer (western column) and a seaman (eastern).
Listed on the walls of the sunken garden are the names of 24,000 British seamen and 50 Australian seamen. Between the bronze plates are stone reliefs, showing allegorical figures representing the Seven Seas. Each figure is different and is accompanied by various fish and a specific shell. It is not clear if Wheeler meant specific seas with each relief. There are various interpretations of the seven seas, an interpretation is seven of the largest bodies of water in the world: The Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Arctic Ocean, the Mediterranean Sea, the Caribbean Sea, and the Gulf of Mexico. Oxford University Press' online dictionary defines them as all the oceans of the world (conventionally listed as the Arctic, Antarctic, North Pacific, South Pacific, North Atlantic, South Atlantic, and Indian Oceans).
