Fort Barrancas, Pensacola

Fort Barrancas (1839) or Fort San Carlos de Barrancas (from 1787) is a United States military fort and National Historic Landmark in the former Warrington area of Pensacola, Florida, located physically within Naval Air Station Pensacola, which was developed later around it.
The hill-top fort, connected to a sea level water battery,

overlooks Pensacola Bay. From 1839–1844, the historic Spanish fort on the hill was reconstructed and dramatically expanded in brick. This is now termed "Fort Barrancas". The older, water battery downhill (Bateria de San Antonio, 1787) has been separately named as "Fort San Carlos".

It is a remnant from the Spanish fortification, the wooden (Spanish: Fuerte) Fort San Carlos de Barrancas of the late 18th century.

Due to changing requirements, the U.S. Army deactivated Fort Barrancas on April 15, 1947 following World War II. Designated a National Historic Landmark (NHL) in 1960, the fort was transferred to the control and administration of the National Park Service in 1971. After extensive restoration during 1971-1980, Fort Barrancas was opened to the public (see below: Timeline).
