The ocean face of Fort Pickens had both barbette (the upper level), and casemate (the lower level, inside the arches) mounted guns. The cannon on the barbette level is an 8-inch Rodman, similar to the type of weapon mounted in the fort late in the Civil War, and a similar weapon was still emplaced there until 1901.
