Battery Worth, built in 1899, is located east of Fort Pickens and west of Battery Langdon. The gun emplacement is named after Brevet Major General William J.

Worth who distinguished himself during the War of 1812, the Second Seminole War, and the Mexican War.

It was originally armed with eight 12-inch mortars, but this proved to be too crowded, and in 1918 half of the guns were removed; by 1942, aircraft could more accurately target ships' decks, thus making the guns obsolete.

At about the same time, Battery Worth became the Harbor Entrance Control Post and the Harbor Defense Command Post, the nerve-center for joint Army-Navy defense of Pensacola Bay during World War II. While the installation never saw combat, all ships entering Pensacola Bay from 1942 through 1945 had to communicate with the Harbor Entrance Control Post to be allowed entrance.

A two-story tower was built in front of the old battery commander's station, and the magazines below were converted into quarters for Army and Navy personnel.

Battery Worth was "deactivated" with the rest of Fort Pickens in 1947.
