Constructed by the Spanish between 1672 and 1695, it was also used to defend the primary trade route to Europe and the Gulf Stream. Throughout its history, the many flags which have flown over it reflect the colonization of the New World and North America.  All changes in occupation of the fort came about not by force, but through military agreements or political treaty. It was occupied by military forces for more than 250 years before being deactivated and taken over by the National Park System.

Made of a form of a shell stone called coquina quarried from Anastasia Island, the fortress is unique in North American architecture. 

The only extant 17th century military construction in the country, it is an example of the bastion system of fortification.
