Fort Barrancas is a historic United States military fort in the area of Pensacola, Florida, located physically on Naval Air Station Pensacola. The hill-top fort, connected to a sea-level water battery, overlooks Pensacola Bay, from what is now Naval Air Station Pensacola. Spanning a multi-century history, the U.S. Army deactivated Fort Barrancas on April 15, 1947. Designated a National Historic Site in 1960, control of the site was transferred to the National Park Service in 1971. After extensive restoration during 1971-1980, Fort Barrancas was opened to the public. The site was first occupied as a fort in 1698 by the Spanish. It has been
occupied and rebuilt by five different governments; Spanish, French, British, Confederate and finally, American.
During the American and Confederate years the fort was home to 19 cannons like the one I've sketched here. If you're ever in the neighborhood, it is well worth a visit!
