Design
Fort Pickens was part of the
Third System of Fortifications, meant to enhance the old earthworks and simple, obsolete designs of the
First and Second System of Fortifications. Fort Pickens was of a Pentagonal design, with broader western walls to provide a wide range of fire over the bay.
The fort had a

. Despite its dilapidated condition, Lieutenant
Adam J. Slemmer, in charge of United States forces at
Fort Barrancas, decided Fort Pickens was the most defensible post in the area. He decided to abandon Fort Barrancas when, around midnight of January 8, 1861, his guards repelled a group of local civilians who intended to occupy the fort. Some historians claim that these were the first shots fired in the Civil War.
On January 10, 1861, the day Florida declared its secession from the Union, Slemmer destroyed over 20,000 pounds of gunpowder at
Fort McRee. He then
spiked the guns at
Fort Barrancas, and moved his small force of 51 soldiers and 30 sailors to Fort Pickens. On January 15, 1861, and January 18, 1861, Slemmer refused surrender demands from

The Confederates attacked the western edge of
Santa Rosa Island on October 9, 1861, in the
Battle of Santa Rosa Island, with a force of over a thousand men. The attack came from the east, after forces landed four miles away. The attack was repelled by artillery and gunfire, and the Confederates retreated with 90 casualties.
Bombardments
After tensions in Pensacola grew, and the Confederates secured posts at Fort McRee and Fort Barrancas, the Federal forces decided to shell the confederate forts. On November 22, two Union warships, the
''Niagara'' and the
''Richmond'', sailed into the bay, and the bombardment began. The attack lasted two days, and the results were in the Union's favor. Fort McRee was nearly destroyed, and the town of

Endicott era
During the late 1890s and early 20th century, the Army had new gun batteries constructed at Fort Pickens. These batteries were part of a program initiated by the
Endicott Board, a group headed by a mid-1880s Secretary of War,
William C. Endicott. Instead of many guns concentrated in a traditional thick-walled masonry structure, the Endicott batteries are spread out over a wide area, concealed behind concrete parapets flush with the surrounding terrain. The use of the accurate, long-range weapons eliminated the need for the concentration of guns that was common in the Third System fortifications. Battery Pensacola was constructed within the walls of Fort Pickens, while other similar concrete batteries were constructed to the east and west as separate facilities. The ruins of these later facilities are also included in the

complex. As at many posts, obsolete weapons were repurposed during World War I; Battery Cooper's
6-inch M1905 guns on
disappearing carriages were removed in 1917, but a piece located at West Point was moved to Battery Cooper in 1976.

Little consideration was given to the preservation of the old fort during the construction of Endicott Batteries. The
parapet

on The south wall of the fort was demolished, along with the officers' quarters beneath. The barbette on the southeast wall was also removed, along with the casemate arches of the southernmost bastion. These changes were made to allow the firing arc of Battery Pensacola's 12-inch Guns to clear with having to raise the battery.
On June 20, 1899, a fire in Fort Pickens' Bastion D reached the bastion's magazine, which contained of powder. The resulting explosion killed one soldier and obliterated Bastion D. The force of the explosion was so great that bricks from Bastion D's walls landed across the bay at Fort Barrancas, more than 1.5 miles (2.4 km) away.

University of South Florida The damage was relatively confined to Bastion D, but the foundations were torn away along with sections of the walls to allow for easier access to the batteries. This proved easier than trying to fit mechanical equipment for Battery Pensacola through the Sally Port.

s were planned for in the interwar era, beginning in 1937. Four 155mm GPF guns were placed around Battery Cooper, two forward, and one to each side, in 1942. The guns used concrete rings for positioning and aiming, which still remain today. The guns, however, have been long since removed. The 155 battery used Battery Cooper's magazines, communications, and other support facilities.
Battery Langdon
Battery Langdon was constructed in 1923, with 12-inch guns meant to complement those already in place at Battery Pensacola. The guns were originally exposed to fire, but the ammunition and command center was stored inside of a reinforced embankment between the guns. The guns were later casemated in 1943.
World War II
Fort Pickens was of interest in World War II to the U.S. Navy, and it was decided that the defenses of the fort needed to be strengthened. A specific threat was German U-Boats

, which were already operating in the Gulf of Mexico.
Battery 234
One addition to Fort Pickens's defense was Battery 234, which was meant to function alongside Battery 233 across the bay on Perdido Key. Many of these batteries were built across the nation, all with the same design, to replace the role of light artillery formerly held by the 3-Inch M1903 guns. Both batteries were designed to equip two 6-Inch M1905 guns in cast-steel casemates. The command center is buried underneath an artificial hill to protect from air attacks. The guns were never fitted during the war, but were donated in 1976 by the Smithsonian and are present today.
Battery Langdon (1943)
To protect from the threat of German dive bombers, Battery Langdon was casemated in 1943. The 12-inch barbette guns that were in place were kept, but 17 feet of concrete was added to create a bomb proof bunker. The bunker was then covered in sand and dirt to create an artificial hill around the battery, for additional protection.
Nearby fortifications
Fort McRee was built on Perdido Key across Pensacola Pass from Fort Pickens. Abandoned by Union forces and taken over by Florida and Alabama militia in January 1861, it was badly damaged by Union bombardment during the American Civil War later that year. Abandoned by Confederate forces, Fort McRee remained in ruins for the next three decades. Although improved in the late 19th century during the run-up to the Spanish–American War
