 Rear Entrance of Emplacement #1 Originally built as a World War II concrete coastal gun battery with two 16" MarkII-M1 guns mounted on M4 Casemated Barbette Carriages (CBC). This battery was a single level battery with the guns located on the same level as the central magazine. Each gun emplacement was casemated with heavy, reinforced concrete overhead protection and earth covering. The central magazine was built between and connecting the gun emplacements so that the powder and shells could be brought directly to the guns using overhead tracks and chain hoists or ammunition carts. See 16" Rifle MarkII-M1.
