Originally built as a temporary World War II coastal gun battery with four 155mm M1918 rapid fire guns mounted on M1918 mobile carriages emplaced on circular Panama mounts. Tubular frames were provided over the gun emplacements for camouflage to conceal the guns. The Battery Commander's Station was placed on a 50' steel tower and disguised as a water tower. Underground shelters and magazines were constructed by troop labor under engineer supervision.
