The ravelin of Fort Barrancas, located on the grounds of the Pensacola Naval Air Station, is another Spanish masonry fortification in Florida besides the Castillo and Fort Matanzas. It is called Battery San Antonio and dates from 1797. It was planned as part of a larger fortification never built by the Spaniards.
